Preparation of CSC-PPy-TiO2 and application in photocatalytic for wastewater treatment

摘要

Polypyrrole modified TiO2 (PPy-TiO2) and coconut shell activated carbon (CSC) were used as raw materials, and Na2SiO3 was used to load PPy-TiO2 on the surface of coconut shell activated carbon. Finally the CSC-PPy-TiO2 photocatalyst was prepared. In this paper, the effects of the degradation effect of methyl orange on the factors such as the addition of PPy-TiO2 and the amount of sodium silicate were discussed. The experimental results showed that CSC-PPy-TiO2 had a good photocatalytic performance, and the decolorization rate of the methyl orange solution of 40mg /L was 88.52% in the light of metal halide lamp with l.Og CSC-PPy-TiO2.
