Realization of Visible Light Photocatalysis by Wide Band Gap Pure SnO2 and Study of In2O3 Sensitization Porous SnO2 Photolysis Catalyst

摘要

SnO2 is a wide band gap semiconductor which has no photocatalysis under visible light. In this study, the disordered porous SnO2 precursor was constructed which showed obvious photocatalysis under visible light irradiation. Its degradation rate to RhB was 51.66% after 100 min, and the amount of hydrogen produced could reach 11.13 mmol·g
