Summary: In this study, an efficient room-temperature gas sensor was synthesized using a microwave-assisted hydrothermal method, with a hybrid nanostructure composed of biomass-derived graphene nanosheets and Ag2S. The hybrid nanostructure showed higher hydrogen sensing efficiency than pure Ag2S nanoparticles, with a maximum response of 45.5% for 150 ppm exposure of hydrogen gas at room temperature. The fast response time and high gas sensitivity of the hybrid sensor were attributed to the diverse attributes and synergetic effect between Ag2S and GNS hybrids.

Summary: The novel ternary nanocomposite Ag-rGO@ZnONR demonstrated excellent photocatalytic performance in the degradation of 2-chlorophenol under solar light irradiation, possibly due to the engineered reduced bandgap and the Schottky barrier at the metal-semiconductor interface facilitating charge separation, as well as the generation of superoxide anions center dot O-2(-) and hydroxyl radicals center dot OH. These interactions, along with pi-pi stacking with the aromatic ring of 2-CP, contributed to the 100% degradation efficiency.

Summary: Graphitic carbon nitride-graphene oxide composite membranes were prepared by filtrating g-C3N4 and a small amount of GO on a porous polymer support. Incorporation of GO nanosheets in g-C3N4 membranes prevented interedge defects or voids, leading to effective separation of H-2 molecules from larger gas molecules. At a GO weight loading of 5%, the composite membrane exhibited enhanced H-2/CO2 separation performance with a H-2 permeance of 3.66 X 10(-6) mol m(-2) s(-1) Pa-1 (H-2/CO2 ideal selectivity: 179.6).

Summary: Detection of ethanol is crucial in various fields due to its explosive, colorless and volatile nature. Metal oxide semiconductors (MOS) gas sensors, particularly those based on indium oxide (In2O3), have gained attention for their low cost and convenient detection. This paper summarizes the strategies used in the last decade to enhance the performance of In2O3-based gas sensors for ethanol detection, including morphology modification, doping, heterojunction construction, and the use of composite materials. The sensing mechanism for ethanol detection by gas sensors is also presented.
