Study on preparation and photocatalytic properties of Cu_2O/TiO_2 composites by precipitation method

摘要

Cu_2O/TiO_2 composite photocatalyst was prepared by precipitation method using Titany 1 sulfate, cupric nitrate and ethylenediamine as raw materials. The photocatalytic performance of photocatalyst was investigated by degradation of Methylene blue solution. The results showed that composite photocatalyst Cu_2O/TiO_2 was successfully prepared by precipitation method. The Cu_2O/TiO_2 composite photocatalys with Cuprous oxide content of 70% performed best photocatalytic activity, the degradation efficiency of Methylene blue under visible light irradation can reach 97% within 40 min.
