Upgrading Type-II Heterojunction to S-Scheme Heterojunction for Enhanced Photocatalytic Toluene Oxidation Performance.
Construction of heterojunctions has been extensively applied to enhance the catalytic performance of TiO2-based semiconductor photocatalysts in the oxidation of volatile organic compounds (VOCs). However, improper charge transfer directions in type-II heterojunctions often result in inadequate redox reactions for O2/·O...
