摘要：

A novel Sb doped SnO2 decorated porous g-C3N4 nanosheet composite photocatalyst, which can be applied in photocatalytic reactions for CO2 reduction and gaseous iso-isopropanol (IPA) oxidation under visible light irradiation, is designed and synthesized. Results demonstrate that the intimate interfacial contact and heterojunction interaction between g-C3N4 and Sb doped SnO2 can significantly boost the photocatalytic efficiencies compared with individual g-C3N4 and Sb doped SnO2 due to the effective separation of photo-generated charge carriers.
