The applications of two-dimensional transition metal dichalcogenides, including molybdenum disulfide (MoS2), have been developing rapidly, due to their unique optoelectronics properties. With different synthesis methods, the semiconducting 2H- and the metallic 1T-MoS2 can be synthesized. However, the environmental implications of these materials remain largely unknown. In this study, we study the short-term and long-term stability of MoS2 nanosheets concurrently with the presence of dissolved organic matter (DOM, e.g., Suwannee River natural organic matter (NOM) and Aldrich humic acid (HA)) under dark or sunlight-irradiated conditions in the aquatic environment. The results indicate that HA quickly binds with MoS2 nanosheets through Mo-C bonding onto MoS2 nanosheets surface. The oxidative deterioration and the phase transformation, 1T to 2H, of MoS2 nanosheets are retarded in the presence of NOM. In the dissolution experiments, MoS2 nanosheets with DOM species have less total mobilized concentration of Mo (TMC of Mo) under dark condition. By contrast, MoS2 nanosheets have enhanced TMC of Mo by adding HA under sunlight irradiation. Overall, the results suggest that the chemical stability and reactivity of MoS2 nanosheets depend on the dispersing media and the types of concurrent DOM in the environment; HA could react with MoS2 directly, while, NOM may protect MoS2 from oxidation and phase transformation.

It was since 2004 that Prof. Andre Geim and Dr. Konstantin Novoselov used mechanical exfoliation method to gain monolayered graphite ---graphene. They have found it has significant electronic behavior and mechanical strength, and opened a route to study the optical and electric behaviors and application of few layered inorganic materials. This study focus on the synthesis of BCN nanosheets via chemical decoration of graphene oxide, hydrothermal exfoliations of boron nitride with the aid of hydrogen peroxide, and the synthesis of few layered structure of molybdenum disulfide by CVD process. In Chapter 1, it is about the basic structure, characteristics and recently progress of graphene, boron carbonitride, boron nitride and molybdenum disulfide nanosheets. In Chapter 2, it is about the experimental sections and investigating instrument. Chapter 3 is about the synthesis of BCN nanosheets, we have successfully doped GO nanosheets with BN via partial substitution of carbon atoms in graphene by boron and nitrogen atoms. Based on the XPS data, the doping concentration of BN increases with the increasing of the reaction temperature. Furthermore, we found that the use of gaseous ammonia allows the doping of graphene allows the doping of graphene with BN to be carried out at the lower temperature. The Raman spectra of the BCN sample synthesized at the various temperatures showed that I(D)/I(G) ratio is proportional to the doping concentration of BN in graphene. Furthermore, the estimate value of graphene nanocrystallite size decreases with the increase in the degree of doping in graphene. Finally, UV spectra of BCN sample with various doping concentration of BN have verified that the band gap of graphene is opened and dependent on atomic composition in nanosheets. For the electrical measurements, we will fabricate the bottom gated field-effect transistors by using the BN-doped graphene. For the studies of BN domain distribution in graphene, we will characterize the BCN samples by using electron energy loss spectroscopy. It is expected that the difference in current between graphene and BN domain can be observed. Chapter 4 is the synthesis of BN nanosheets, we have succesfully decorate BN with OH group via hydrothermal reactions with hydrogen peroxide, and sequentially exfoliated via sonication to gain BN nanosheets. Based on the AFM data, lateral size and height of BN nanosheets decreaes with increasing the reaction temperature.UV spectra of BN nanosheets have verified increased solubility with increased OH group . Finally, we use BN nanosheets to absorb perylene-3,4,9,10-tetracarboxylic acid tetrapotassium salt (PTAS) molecule with π-π interaction and desorption with KOH. We found that with the increase of OH concentration desorption concentration decreases caused by blocking of OH group. Chapter 5 is the synthesis of MoS2 layered structure, large-area MoS2 films are directly synthesized on SiO2/Si substrates with chemical vapor deposition. It is noteworthy that the growth of MoS2 is not unique to SiO2 substrates and it is also observed on other insulating substrates such as sapphire. The as-synthesized films are consisted of monolayer, bilayer and other few-layer MoS2. Chemical configurations, including stoichiometry and valence states of MoS2 layers are confirmed with XPS. Raman spectra and PL performance of the monolayer MoS2 are presented. TEM and SAED demonstrate that the monolayer MoS2 exhibits six-fold symmetry hexagonal lattice and high crystallinity. The electric measurement for the bottom-gate transistor shows a N-type semiconductor behavior and the on-off current ratio is approximately 1 x 104. The seeding approach can be further used to grow other transition metal dichalcogenides. Finally, Chapter 6 is the conclusion and future work.

In organic photovoltaic (OPV) devices, more effective transfer of dissociated electrons and holes from the active layer to the respective electrodes will result in higher fill factors (FF) and short-circuit current densities (Jsc) and, thus, enhanced power conversion efficiencies (PCE). The PCE of OPVs is affected not only by active layer but also transport layer. In my study, I specialize in developing the electron transport layer (ETL) by doping two-dimensional (2D) transition-metal dichalcogenide (TMD) materials for OPV devices. In the first part study, we incorporated molybdenum disulfide (MoS2) nanosheets into sol–gel processing of zinc oxide (ZnO) to form ZnO:MoS2 composites for use as ETLs in inverted polymer solar cells featuring a binary bulk heterojunction active layer. We could effectively tune the energy band of the ZnO:MoS2 composite film from 4.45 to 4.22eV by varying the content of MoS2 up to 0.5 wt%, such that the composite was suitable for use in bulk heterojunction photovoltaic devices based on poly[bis(5-(2-ethylhexyl)thien-2-yl)benzodithiophene–alt–(4-(2-ethylhexyl)-3-fluorothienothiophene)-2-carboxylate-2,6-diyl)] (PTB7-TH):phenyl-C71-butryric acid methyl ester (PC71BM). In particular, the PCE of the PTB7-TH:PC71BM (1:1.5, w/w) device incorporating the ZnO:MoS2 (0.5 wt%) composite layer as the ETL was 10.1%, up from 8.8% for the corresponding device featuring ZnO alone as the ETL—a relative increase of 15%. Incorporating a small amount of MoS2 nanosheets into the ETL altered the morphology of the ETL and resulted in enhanced current densities, fill factors, and PCEs for the devices. We used ultraviolet photoelectron spectroscopy (UPS), synchrotron grazing-incidence wide-/small-angle X-ray scattering (GIWAXS/GISAXS), atomic force microscopy (AFM), and transmission electron microscopy (TEM) to characterize the energy band structures, internal structures, surface roughness, and morphologies, respectively, of the ZnO:MoS2 composite films. For the second part study, a new universal ETL that involves doping hydrogen-plasma treated tungsten disulfide (WS2) nanosheets into ZnO for polymer/fullerene or small molecule OPVs was prepared. A hydrogen-plasma treatment was used to alter the structures of WS2 nanosheets such that the W6+ content was converted into W4+; then ZnO:WS2 nanosheets composites were prepared to form ETLs. The energy band of the ZnO:WS2 films could be tuned from 5.15 to 4.60 eV by varying the concentration of the WS2 nanosheets up to 0.5 wt%. It was found that ZnO:WS2 ETLs exhibited superior charge transport properties than those of the pristine ZnO layer because of the structure changes, as determined from the X-ray scattering characterizations. OPVs incorporating active layers of PTB7-TH/PC71BM and PTB7-TH/IDIC blends exhibited their power conversion efficiencies of 10.3% and 6.7%, respectively, with the incorporation of 0.3 wt% of the WS2 nanosheets, up from 8.9% and 5.4% for the corresponding devices featuring pristine ZnO—relative increases of 16% and 24%, respectively. This study demonstrates the effectiveness of hydrogen-plasma treatment for altering the surface structures of 2D TMD nanosheets, and paves a way for the composite ETLs for use in OPVs.

In recent years, two-dimensional materials have widely been used to replace traditional fillers in mix matrix membranes (MMMs). With high affinity for carbon dioxide (CO2), molybdenum disulfide (MoS2) provides great potential to produce MMMs with high permeability and sufficient selectivity in gas separation application. However, it is still a challenge to estimate the performance of using MoS2 as functional fillers in MMMs due to the complex structure. An aim of our study is to develop a methodology to appropriately simulate MoS2-contained MMMs system and also predict the separation performance. We modified the force field parameters in PCFF, which is built in commercial software Materials Studio 2017 R2, and applied the restraint method for a better description of MoS2 nanosheet structure. In this study, Pebax-1657 was chosen as the polymer matrix and a series of MMMs models with MoS2 loading ranging from 0wt% to 20wt% were constructed. By applying molecular dynamics (MD) and Monte Carlo (MC) simulations, we respectively determined the diffusivity and solubility coefficient of CO2 and N2 within the MMMs. Then, to investigate the influence of MoS2 loading on the performance, the permeability via the solution-diffusion mechanism for each gas as well as the ideal gas selectivity for binary gas mixtures were examined. The results reveal that the addition of MoS2 could significant increase the solubility of CO2 at low loading and the upward trend seems to level off with additional loading to 20wt%. Compared to the results of diffusivity, it was found that the solution step dominates the solution-diffusion process. By increasing the MoS2 loading from 0wt% to 20wt%, the permeability of CO2 significantly increased from 32.05 to 129.64 Barrer without sacrificing the permeability selectivity of CO2/N2. Therefore, our results indicate that, at appropriate MoS2 loading, the incorporation of MoS2 could enhance the CO2 capture performance of Pebax-1657 membrane. Our study provides a method to build representative MoS2-contained MMMs models and predict the performance. The results can help followers to efficiently conduct the experiment and design MMMs of other polymer bases as well.
