Nan Zhang et al.

Summary: WO3-TiO2 heterostructural nanofibers exhibited improved response, selectivity, and lower detection limit to xylene gas sensing compared to pure materials. The enhancement in performance is attributed to the formation of heterojunction between TiO2 and WO3, as well as the conversion between W6+ and W5+.

Construction of In2O3/ZnO yolk-shell nanofibers for room-temperature NO2 detection under UV illumination

Chaohan Han et al.

Summary: A room-temperature NO2 sensor with greatly enhanced sensitivity and rapid response/recovery speed under ultraviolet (UV) illumination has been proposed. The sensor based on In2O3/ZnO yolk-shell nanofibers exhibits remarkable sensitivity and quick response/recovery time, outperforming the performance in dark conditions. These results were attributed to the improved photo-generated charge separation efficiency and increased reactive sites and gas adsorption provided by the heterojunction effect of In2O3/ZnO yolk-shell nanofibers.

High performance acetaldehyde gas sensor based on p-n heterojunction interface of NiO nanosheets and WO3 nanorods

Umesh T. Nakate et al.

Summary: A chemi-resistive sensor based on P-N heterojunction was designed by incorporating NiO nanosheets into WO3 nanorods. Among the sensors fabricated with different weight ratios, NW2 exhibited the highest response for 100 ppm acetaldehyde concentration at 250 degrees C and showed good stability and repeatability. The high performance of NW2 sensor is attributed to the formation of the p-n heterojunction between NiO and WO3, making it a promising candidate for acetaldehyde sensing applications.

Perovskite-structured LaCoO3 modified ZnO gas sensor and investigation on its gas sensing mechanism by first principle

Wenbo Qin et al.

Summary: LaCoO3 nanoparticles were synthesized by sol-gel method and modified on the surface of ZnO to prepare LCO/ZnO nanometer flake materials with improved gas-sensitive response. The LCO/ZnO sensor showed significantly enhanced response to ethanol gas, shorter response time and recovery time at an optimal operating temperature of 320 degrees C. Analysis of the sensitization mechanism revealed that the improved sensing performance was attributed to the increase of surface adsorbed oxygen content and the strong catalytic oxidation activity of LCO.
