Synthesis of poorly crystalline, randomly oriented rag-like structures of molybdenum disulfide has been reported starting from aqueous solutions of ammonium molybdate, and thioacetamide in presence of sodium dodecyl sulfate via calcination of the amorphous precipitates, obtained through acidification of the in situ generated intermediate of ammonium tetrathiomolybdate. X-ray photoelectron spectroscopy, UV-visible spectroscopy, and X-ray diffraction of the calcined samples reveal the formation of single-phase MoS2, while the amorphous precipitates have been found to be a mixture of Mo2S5, MoS3, and a trace amount of H2MoS4. Highly folded and disordered layers of rag-like MoS2 have been confirmed through high-resolution transmission electron microscopy. The electrical conductivity for the cold pressed pellet of the MoS2 sample is found to be significantly higher than that of 2H-MoS2 and increases further on annealing.

Abstract With industrialization, industrial wastewater, especially dye wastewater, flows into water resources, causing serious water pollution problems. Therefore, it is urgent to quarantine organic dyes from wastewater and improve water resource quality. Molybdenum disulfide (MoS2) nanomaterials are widely used in water treatment fields because of their special structure and properties; a case in point is pollutant adsorption, photocatalysis, membrane separation, and antibacterial treatment. In this paper, ammonium molybdate and thiourea were used as precursors; while the relative concentration of thiourea was increased, MoS2 nanopowders were prepared by the hydrothermal method. Then the prepared MoS2 nanopowders were characterized. The adsorption performance of organic dyes was preliminarily studied with the rhodamine B dye adsorption model.

Recently, molybdenum disulfide (MoS2), have been explored as photothermal materials for solar evaporation. However, the optimum phase for photothermal material, 1T-MoS2 or 2H-MoS2, is still debatable. In this work, we observed the morphological and structural properties of MoS2 prepared by a simple hydrothermal process at 200 °C in three different growth times (16, 20, and 24 hours) using Na2MoO4·2H2O (sodium molybdate) as a Mo precursor, and CS(NH2)2 (thiourea) as S precursor. MoS2 nanoflowers were successfully prepared with nanosheets petals and its diameter increased from 0.4 to 2.8 and 4.5 as the growth time increased from 16 to 20 and 24 hours. The increase in growth time also led to improve the Mo:S ratio from 1:8 to 1:5 and facilitate the phase transformation from 1T to 2H as indicated by the shifting of (002) diffraction peak from 9.25° to higher degrees (12.98°, and 14.12°).

Molybdenum disulfide (MoS2) catalyst on carbon support from varying ratio of sawdust and sugarcane bagasse has been successfully synthesized by hydrothermal carbonization and calcination process. Hydrothermal carbonization of lignocellulosic structure into carbon support is investigated at 200 oC for 24 hr and calcination at 600 °C for 2 hr. The precursor of MoS2 catalyst is prepared using thiourea (CH4N2S) and ammonium molybdate tetrahydrate ((NH4)6Mo7O24 . 4H2O) loaded on carbon support. The lignocellulosic structure as hemicellulose and cellulose is changed at high temperature via hydrothermal carbonization and calcination. The distribution of molybdenum disulfide on carbon support is varied based on morphology and functional group of carbon support. The morphology and functional group were analyzed using Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). It shows that carbon support at equal ratio (1:1) of sawdust and sugarcane bagasse is an optimum ratio with high distribution of molybdenum disulfide catalyst on carbon support.

The ternary nanocomposite of silver particles decorated N/S dual-doped graphene and molybdenum disulfide microspheres (Ag-MoS2/NSG) is prepared by hydrothermal-chemical reduction method with graphene quantum dots (GQDs) as additives and graphene oxide, sodium molybdate and silver nitrate as main raw materials. For comparison, the binary composites of Ag-MoS2, Ag-NSG and MoS2/NSG are also prepared and discussed. In addition, the physicochemical and electrochemical properties of GQDs are studied, and the dynamic analysis of Ag-MoS2/NSG is also carried out. Results show that the ternary composite of Ag, MoS2 and NSG can effectively prevent the lamellar superposition and agglomeration of graphene, which effectively improves the specific surface area and conductive properties of the composite. The specific capacitance of Ag-MoS2/NSG is 1124.3 F·g−1 at 10 mV·s−1, and the specific capacitance retention is 95.2% after 10000 constant current charge/discharge loops. The asymmetric button supercapacitor device assembled with NSG and Ag-MoS2/NSG has a maximum energy density of 82.5 Wh·kg−1 (900 W·kg−1).

Large amounts of nitroaromatic compounds are discharged into the natural environment, leading to environmental pollution. The detection and removal of nitroaromatic compounds are therefore important environmental issues. In this study, the hybrid of molybdenum disulfide (MoS2) and graphene (GR) was synthesized using a facile hydrothermal method. Sodium molybdate was selected as the precursors for MoS2. While thiourea was used as reductant and sulfur sources at the same time. Samples were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N2 adsorption, Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), and Raman microscope. Compared to pure MoS2, the obtained MoS2/GR hybrid showed improved activity for electrochemical detection and chemical reduction of 4-nitrophenol. The activity enhancement should be due to the addition of GR, which could improve the conductivity as well as provide more active sites. The MoS2/GR hybrid could therefore provide new multi-function catalyst for environment protection.

One-step and controlled pH hydrothermal synthesis of transition metal disulfide using double molybdenum sources to synthesize MoS2 nano-flowers at low temperature was first reported. Anhydrous molybdenum pentachloride (MoCl5) and four sulfur ammonium molybdate ((NH4) 6Mo7O24•4H2O) were the molybdenum source and CS (NH2) 2 was the sulfur source. Through hydrothermal method, MoS2 was obtained at 180 °C. The pH value of system was controlled by adjusting the molar ratio of MoCl5 and (NH4) 6Mo7O24•4H2O. The products were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), surface area (BET) and transmission electron microscopy (TEM). The results show that the products were hexagonal MoS2 with a high crystalline and flower-like structure consisted of small particles. The thickness of petals is a few to tens of nanometers. By changing the molar ratio of molybdenum sources, the resultant phase from the mixed phase transited to the pure phase and the purity of synthetic MoS2 crystal increaseed.

The as-synthesized MoS2 samples were characterized by x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and transmission electron microscope (TEM); the effects of addition of CTAB on reaction process and resulted particles have been investigated in detail. It has been shown that the addition of CTAB can not only prevent the agglomeration of the particles, but regulate their morphologies and phase compositions. The resulting 2H-MoS2 with hexagonal phase and average size of 10-20nm can be directly obtained at low hydrothermal temperature needless of high-temperature sintering and inert gas protection.

In this work, poly(sodium 4-styrenesulfonate) (PSS) modified molybdenum disulfide quantum dots (MoS2-PSS QDs) were synthesized via a simple hydrothermal method using l-cysteine and anhydrous sodium molybdate as precursors and PSS as a modification reagent, and a selective and sensitive fluorescent sensing method for the determination of p-nitrophenol (p-NP) based on their UV emission was developed. The obtained MoS2-PSS QDs have an obvious UV emission peak (390 nm) with quantum yield of 5.13%. The strong absorption peak of p-NP at 400 nm has large spectral overlap with the UV emission peak (390 nm) of MoS2-PSS QDs. Because of this p-NP absorption, the fluorescence of MoS2-PSS QDs at 390 nm is quenched with the introduction of p-NP via the inner filter effect (IFE) and the decreased fluorescence intensity was linearly proportional to the p-NP concentration in the range of 1–20 μmol/L, leading to a detection limit of 0.13 μmol/L for p-NP. The MoS2 QDs-based fluorescent probe for p-NP is sensitive and selective and was successfully applied in the determination of p-NP in the pond water samples with satisfactory results.

Molybdenum disulfide (MoS2) is a nontoxic, environmentally friendly, abundant semiconducting material which is widely used in the areas of hydrogen storage, gas sensing and, solid super lubricant. It has three major phases called 1-T MoS2, 2-H MoS2 and 3-R MoS2. Among them 2-H MoS2 form is the stable form which has a hexagonal phase structure with an activated edge. Therefore, Activation of the material is possibly changing by making differences on nature of material edges. In this work, we report that influence of duration of hydrothermal process toward the growth of edge sites of 2-H molybdenum disulfide nanocomposites. In this study, we have synthesized three 2-H MoS2 nanostructures by facile hydrothermal route by using Ammonium molybdate, Thioacetamide, and urea as the basic precursors. All the samples were prepared at 200 ℃ temperature by changing the duration of hydrothermal process as 24h, 36h and, 48h. The samples were characterized by powder X-ray diffraction (PXRD) and Scanning electron microscope (SEM) for the phase confirmation and morphological characterizations respectively. Next, Electrochemical characterizations were carried out by using linear sweep voltammetry under the basic medium. Powder X-ray diffraction results confirmed that the prepared three products were at the Hexagonal phase of MoS2 with minor level of impurity. The SEM images show that the as-prepared structures have a Plate-like structure with sharped edges. Then the Linear sweep voltammetry of the materials verified that the high number of sharped edges of MoS2 nanocomposites leads to excellent activity for Hydrogen evaluation reaction (HER). When compared to others, 48 h material has a higher number of sharped edge sites and the best performances in HER. Finally, the sharpness and amounts of edge sites are possible to control with the duration of hydrothermal process and 2-H MoS2 with more number of sharped edge sites were found to increase the performances of HER.

Molybdenum disulfide (MoS2) is an actively pursuing material of the 2D family due to its semiconducting characteristics, making it a potential candidate for nano and optoelectronics application. MoS2 growth from molybdenum and sulphur precursors by chemical vapor depositions (CVD) is used widely, but molybdates’ conversion into MoS2 via CVD is overlooked previously. Direct growth of MoS2 on the desired pattern not only reduces the interfacial defects but also reduces the complexities in device fabrication. In this work, we combine the wet synthesis and chemical vapor deposition method where sodium molybdate and L-cysteine are used to make a solution. With the dip coating, the mixture is coated on the substrates, and then, chemical vapor deposition is used to convert the chemicals into MoS2. Raman spectroscopy revealed the presence of oxysulphides (peaks number value) other than A 1 g and E 2 g 1 , where heat treatment was performed in the presence of Ar gas flow only. On the other hand, the films reducing in the presence of sulphur and argon gas promote only A 1 g and E 2 g 1 peaks of MoS2, which confirms complete transformation. XRD diffraction showed a very small change in the diffraction peaks and value of strain, whereas SEM imaging showed the flakes formation for MoS2 samples which were heated in the presence of sulphur. X-ray photoelectron spectroscopy is also performed for the chemical composition and to understand the valence state of Mo, S, and O and other species.

We report the thermal stability of spherically shaped cobalt-promoted molybdenum disulfide (Co/MoS2) nano-catalysts from in-situ heating under electron irradiation in the scanning transmission electron microscope (STEM) from room temperature to 550 °C ± 50 °C with aid of Fusion® holder (Protochip©, Inc.). The catalytic nanoparticles were synthesized via a hydrothermal method using sodium molybdate (Na2MoO4·2H2O) with thioacetamide (CH3CSNH2) and cobalt chloride (CoCl2) as promoter agent. The results indicate that the layered molybdenum disulfide structure with interplanar distance of ~0.62 nm remains stable even at temperatures of 550 °C, as observed in STEM mode. Subsequently, the samples were subjected to catalytic tests in a Robinson Mahoney Reactor using 30 g of Heavy Crude Oil (AGT-72) from the golden lane (Mexico’s east coast) at 50 atm using (ultrahigh purity) UHP hydrogen under 1000 rpm stirring at 350 °C for 8 h. It was found that there is no damage on the laminar stacking of Co/MoS2 with temperature, with interlayer spacing remaining at 0.62 nm; these sulfided catalytic materials led to aromatics rise of 22.65% and diminution of asphaltenes and resins by 15.87 and 3.53%, respectively.

Hydrogen (H2) shows great potential in reducing greenhouse gas emissions and improving energy efficiency due to its environmentally friendly nature and high gravimetric energy density [1]. It can be generated via electrochemical water splitting based on the hydrogen evolution reaction (HER). It is well known that Pt-group metals (PGMs) are excellent catalysts for HER, but their broad adoption is limited by high cost and scarcity. Recently, two-dimensional (2D) molybdenum disulfide (MoS2) is regarded as a promising alternative to PGMs due to its large surface area, rich active sites, and ideal hydrogen adsorption energy [2]. However, its practical application is hindered by the intrinsically low electrical conductivity arising from the semiconducting nature of2H phase MoS2[3]. On the other hand, 2D Ti3C2 MXene with high electrical conductivity, excellent hydrophilicity, and large interlayer distance has been intensively investigated in energy storage devices lately[4]. Compared with charge-neutral graphene, MXene exhibits a negatively charged surface due to the existence of numerous surface functional groups (-OH, -O, -F, etc.), which not only enhances the dispersion of MoS2 precursors but also promotes MoS2 nucleation, making it a superior template for MoS2 synthesis. Nevertheless, undesired oxidation of MXene occurs in aqueous solutions [5], reducing the overall catalyst stability. To address the above issues, we employed a one-step solvothermal method using DI water/DMF as bisolvent and constructed metallic 1T phase-enriched MoS2/MXene composite as HER catalyst. The advantages of using bisolvent lie in twofold: (i) suppress undesired oxidation and thus preserve high conductivity of MXene framework, and (ii) improve MoS2 electrical conductivity by inducing 2H to 1T phase transition. The introduction of metallic 1T phase MoS2 is triggered by ion intercalation. Specifically, during the synthesis, both ammonium molybdate (Mo precursor) and DMF can act as abundant sources of NH4+ which can intercalate into MoS2 layers. This process stimulated charge imbalance between Mo3+ and Mo4+ and led to the S plane sliding [6]. As a result, crystal structure distortion and therefore phase transformation of MoS2 occur along with interlayer distance expansion. To further improve the catalyst conductivity, carbon nanotubes (CNTs)were introduced into the binary composite as crosslinks to bridge the 2D islands. As a result, a low overpotential (169 mV) and Tafel slope (51 mV/dec) along with the highest turnover frequency (7 s-1 at -0.23V vs. RHE) and an ultralong lifetime (72 hours) was successfully achieved. The origin of the outstanding HER performance of the ternary composite can be ascribed to: (i) the prevention of 2D layer restacking as well as the enlarged surface area due to the 2D/2D MoS2/MXene integration and ion intercalation. This will promote the contact between electrolyte and catalyst, resulting in an increased hydrogen ion adsorption; (ii)the vertical growth of MoS2 flakes on MXene template which increases the exposure of MoS2 edge planes, maximizing the total number of active sites; (iii) the synergistically enhanced conductivity because of the formation of hybrid 1D/2D conductive network via the integration of 1T-phase metallic MoS2, conductive MXene backbone with suppressed oxidation along with the CNT crosslinks, minimizing the charge transfer resistance at the electrode/electrolyte interface. This work demonstrated an effective strategy for low-dimensional material structure-property engineering with the aim of optimizing the HER performance which will shed light on the development of the next-generation PGM-free HER electrocatalysts.

AbstractMolybdenum disulfide (MoS2) is an effective friction modifier that can be formed on surfaces from oil-soluble lubricant additives. Different additive chemistries can be used to form MoS2 on a surface. The tribofilms formed from three different molybdenum additives (MoDTC Dimer, MoDTC Trimer, and molybdate ester) were studied in additive monoblends and fully formulated systems. The resulting tribofilms were then characterized by Raman spectroscopic spatial mapping, XPS, and FIB-TEM. The distribution of MoS2 on the surface was much more sparse for the molybdate ester than the other additives. No crystalline molybdenum oxides were observed by Raman spectroscopy, but their presence was inferred from XPS analysis. XPS analysis showed very similar distributions of Mo oxidation states from each additive, such that the chemical nature of the films formed from all of the additives is likely similar. Each of the additive tribofilms was observed to have MoS3 vibrations in Raman and persulfide XPS peaks associated with amorphous MoS3, as such this species is presented as a common frictional decomposition product for all the additives. The MoDTC trimer is more able to produce this amorphous species on the contacting surfaces due to its structural similarities to the co-ordination polymer MoS3. Graphical Abstract

Abstract 2D semiconductor material, Molybdenum Disulfide (MoS2), with unique properties similar to that of graphene, is considered as a potential candidate for photocatalytic and antimicrobial applications. In the current work, MoS2 was prepared by a simple hydrothermal method using sodium molybdate and thiourea as precursors. Thecalculated band gap values of MoS2 grown at 200 ˚C and 180 ˚C were 2.1 eV and 1.98 eV, respectively. Flower like morphology was observed from FESEM analysis. Multi layered structure of MoS2 was confirmed from the difference the peak value obtained for A1g and E12g vibrational modes observed from Raman spectra. The reusability of the synthesized MoS2 was analyzed against MB dye degradation. The pristine MoS2 removed ~98% of the dye molecules from the water under the minimum wattage (20W) of visible light in 180 minutes. The catalyst retained good stability even after the third degradation, confirming the reusability of MoS2. The disk diffusion method was used to evaluate the antimicrobial activity of the grown MoS2 nanostructures. The gram-positive and gram-negative bacteria used in present study were Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli and Bacillus serius. Investigation of the antibacterial activity of MoS2 against these four different pathogens was carried out in detail.
