TiO Nanosphere/MoSe Nanosheet-Based Heterojunction Gas Sensor for High-Sensitivity Sulfur Dioxide Detection.

With the growing severity of air pollution, monitoring harmful gases that pose risks to both human health and the ecological environment has become a focal point of research. Titanium dioxide (TiO) demonstrates significant potential for application in SO gas detection. However, the performance of pure TiO is limited.

Room-Temperature Benzene Sensing with Au-Doped ZnO Nanorods/Exfoliated WSe Nanosheets and Density Functional Theory Simulations.

A gold-doped zinc oxide (Au-ZnO)/exfoliated tungsten diselenide (exfoliated WSe) nanocomposite-based gas sensor toward benzene with high sensing properties was demonstrated. Epoxy resin was used as the matrix of the Au-ZnO/exfoliated WSe nanocomposite sensor. The straw-shaped Au-ZnO was synthesized by the hydrothermal method, and WSe nanosheets (NSs) were prepared via hydrothermal and liquid-phase exfoliation methods.
