Abstract:

Semiconductor-based gas sensors are of great interest in both industrial and research settings, but poor selectivity has hindered their further development. Current efforts including doping, surface modifications and facet controlling have been proved effective. However, the “methods-selectivity” correlation is ambiguous because of uncontrollable defects and surface states during the experiments. Here, as a case study, using a DFT method, we studied the adsorption features of commonly tested gases—CH2O, H2, C2H5OH, CH3COCH3, and NH3—on facets of ZnO(0001¯), ZnO(101¯0) and ZnO(101¯1).

Abstract:

Many new sustainable porous materials were developed for gas adsorption applications. Common materials such as activated carbon, clay materials and metal organic framework (MOF) that utilized as potential porous adsorption materials were studied. The article was also discussed on the fabrication methods of porous materials. Adsorptions of flue gas using porous materials were reviewed. It was found that the adsorption properties of porous materials were highly dependent on surface area, selectivity and impregnation. Low cost porous adsorbents such as clay and fly ash were also reviewed as poten

Abstract:

Selective gas adsorption plays an important role in adsorptive separation of gases and scavenging unfavorable or hazardous gases. The use of cost-effective and environmentally friendly materials for selective gas adsorption has become one of the most pressing needs today. The development of new adsorbents is essential but difficult due to the selectivity and efficiency requirements for practical application. As potential scavengers, metal–organic frameworks (MOFs) have drawn great attention. In this review, the current progress of science and technology development of MOFs on selective gas sca

Abstract:

The simulation of carbon dioxide (CO2)-methane (CH4) mixed gas adsorption and the selectivity on zeolite 4A using Aspen Adsorption were studied. The influence of temperature ranging from 273 to 343 K, pressure up to 10 bar and various compositions of CO2 in the binary system were simulated. The findings of the study demonstrate that the models are accurate. In addition, the effects of various key parameters such as temperature, pressure, and various compositions of binary gases were investigated. The highest CO2 and CH4 adsorption are found at 273 K and 10 bar in the Langmuir isotherm model wi

Abstract:

Porous metal–organic framework [Zn2(ttdc)2(bpy)] (1) based on thieno[3,2‑b]thiophenedicarboxylate (ttdc) was synthesized and characterized. The structure contains intersected zig-zag channels with an average aperture of 4 × 6 Å and a 49% (v/v) guest-accessible pore volume. Gas adsorption studies confirmed the microporous nature of 1 with a specific surface area (BET model) of 952 m2·g–1 and a pore volume of 0.37 cm3·g–1. Extensive CO2, N2, O2, CO, CH4, C2H2, C2H4 and C2H6 gas adsorption experiments at 273 K and 298 K were carried out, which revealed the great adsorption selectivity of C2H6 ove

Abstract:

Ideal Adsorbed Solution Theory (IAST) is a predictive model that does not require any mixture data. In gas purification and separation processes, IAST is used to predict multicomponent adsorption equilibrium and selectivity based solely on experimental single-component adsorption isotherms. In this work, the mixed gas adsorption isotherms were predicted using IAST calculations with the Python package (pyIAST). The experimental CO2 and CH4 single-component adsorption isotherms of Mg-gallate were first fitted to isotherm models in which the experimental data best fit the Langmuir model. The pres

Abstract:

To realize a high response and high selectivity gas sensor for the detection dissolved gases in transformer oil, in this study, the adsorption of four kinds of gases (H2, CO, C2H2, and CH4) on Pd-graphyne was investigated, and the gas sensing properties were evaluated. The energetically-favorable structure of Pd-Doped γ-graphyne was first studied, including through a comparison of different adsorption sites and a discussion of the electronic properties. Then, the adsorption of these four molecules on Pd-graphyne was explored. The adsorption structure, adsorption energy, electron transfer, elec
