Abstract:Light assistance and the construction of heterojunctions between two semiconductors with matching band structures are effective strategies for obtaining efficient gas sensors. Recently, Z-scheme heterojunctions have shown marked potential in promoting the separation and transfer of photogenerated carriers as well as possessing strong redox capability. In this study, two types of nanocomposites of WO 3 /CeO 2 and CeO 2 /WO 3 with Z-scheme heterojunctions were designed and prepared with WO 3 and CeO 2 as host ma… Show more
