The preparation and photocatalytic activity of CdS/(Cal-Ta2O5-SiO2) composite photocatalyst under visible light

CdS/(cal-Ta2O5-SiO2) composites with imitate junction were successfully prepared by wet chemical method with multi-step load. As a catalyst in the photocatalytic degradation of rhodamine B and hydrogen generation under visible light, enormous activity can be obtained over as-prepared CdS/(Ta2O5-SiO2) and CdS/Ta2O5-commercial.353
