The adsorption and electronic properties of molecules (NO, H2S, SO2, NO2, NH3, N2, CO, CH4, CO2, H2O) on the C6N7 monolayer were systematically studied to explore possibilities C6N7-based toxic gas sensor scavenger by using first-principles methods. We found only NO, SO2 are adsorbed with high strength (ranging -0.853~-0.931 eV), meanwhile other all weak physisorption Ead -0.193~-0.547 eV. NO H2S could remarkably affect monolayer, indicating it is highly sensitive selective towards H2S....
Dehydration of lactic acid was performed over various metal sulphates. BaSO4 found to show an efficient activity for dehydration acrylic due the moderate acidity on its surface. Under optimal conditions, 99.8% conversion and 74.0% selectivity were achieved catalyst.
The hydrodeoxygenation of lactic acid (LA) to propionic (PA) is great significance for the conversion biomass valuable products; however, it remains a challenge because trade-off between LA and PA selectivity. Here, we prepared ultrathin MoS2 nanosheets containing rich sulfur vacancies by lithium exfoliation. With increase exfoliation time, vacancy in accordingly increased adsorption activation on enhanced. Increasing lowered valence band simultaneously enhanced dissociation H2 molecule....
Abstract Thiosulfate is a green leaching agent used in the hydrometallurgical process because it both environmentally benign and can form required soluble ion complexes. In this article, novel method for synthesis of CdS–Ag 2 S nanocomposites from solution relevant complexes via ultrasound-assisted ultraviolet (UV) photolysis was proposed. An analysis mechanism revealed that undergo series photochemical reactions. The were synthesized by co-precipitation under UV-C irradiation....
Solar-driven interfacial evaporation is widely viewed as a promising technology for seawater desalination and other wastewater purifications thanks to its low cost environmentally friendly features. Here, we proposed high-index-faceted NiS (NiWO4-NiS) light absorbent photothermal conversion. In water tests, the NiWO4-NiS flat membrane evaporator (NiWO4-NiS 2D evaporator) exhibited markedly higher rate than ordinary evaporator. To disclose reason, various characterizations were performed....
Decarbonylation of lactic acid to acetaldehyde over several solid catalysts was investigated. Among the tested catalysts, aluminum sulfate has an excellent activity. In order further understand main reason which influenced catalytic activity, NH3-TPD used estimate acidity catalyst. According total amount, a moderate amount. Heteropolyacids have strong caused serious carbon deposition on surface resulting in rapid deactivation catalysts. Besides, FT-IR, XRD, and SEM were also utilized...
Glucose, xylose and arabinose are the three most abundant monosaccharide found in lignocellulosic biomass. Effectively simultaneously utilization of these sugars by microorganisms for production biofuels bio-chemicals is essential toward directly fermentation In our previous study, recombinant Bacillus subtilis 168ARSRCPΔacoAΔbdhA strain was already shown to efficiently utilize acetoin, with a yield 0.36 g/g xylose. current subtilis168ARSRCPΔacoAΔbdhA further engineered produce acetoin from...
The gas-sensing application potential of the TO8C monolayer for target gases (NO, NO2, CO, CO2, NH3, CH4, H2O, and H2) was systematically investigated via DFT calculations. Only NO NO2 adsorption can tune electronic properties monolayer. Since weak strength is unfavorable sensor device, E-field modulation applied. Except as enhancement into desired ranges −0.14 ∼ −0.21 V/Å (0.08 0.12 −0.26 −0.29 NO2) makes semiconducting transfer conducting properties, indicating sensitivity towards also...
