| Abstract: | A series of TiO2/Cu2O mixed oxides are prepared.Photocatalytic degradation of acid brilliant scarlet GB over these composite oxides is performed under visible irradiation,and effects of composition of catalysts and H2O2 are studied.The result shows that among these composite oxides,the 5%TiO2-Cu2O has the highest activity,and the decolorization rate of acid brilliant scarlet GB is 86% and degradation percentage of COD reaches 65% over TiO2/Cu2O with a little H2O2. |
