Preparation and Photocatalytic Properties of CdS/ZnS/TiO₂ Photocatalyst

Abstract:

CdS/ZnS/TiO₂ composite photocatalyst was prepared by sol-gel and immersion method. The optimum preparation conditions were as follows: the mole ratio of XS (CdS, ZnS) and TiO₂ was 1:100; the mole ratio of CdS and ZnS was 1:1; calcined temperature 500°C; calcined time 1h. The optimum photocatalytic reaction conditions were as follows: the concentration of methyl orange 20mg/L, pH 5-7 and the catalyst dosage 2g/L. The removal rates of color and TOC were 84.3% and 54.2% using CdS/ZnS/TiO₂ under the Visible light irradiation, respectively.
