摘要 制备了在可见光照射下具有较高催化活性的系列TiO2/Cu2O光催化剂,并用其在可见光下光催化降解酸性大红。研究了TiO2含量和H2O2对光催化反应的影响。结果表明5%TiO2/Cu2O的光催化活性最好,在加入少量的H2O2情况下酸性大红的脱色率可达到86%,化学需氧量(CODC r)去除率达到65%。 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.
