摘要
用CuCl水解法制备Cu2 O粉末 ,用透射电镜 (TEM)和X衍射 (XRD)对Cu2 O粒子进行了表征。在仿太阳光源的照射下 ,研究了Cu2 O对水中难降解有机污染物对硝基苯酚的光催化降解效果。结果表明 ,在 8h内 ,对硝基苯酚几乎完全降解。在催化剂用量为 0 .2g时 ,对浓度为 2 2 .4mg/L的 2 0 0mL对硝基苯酚溶液有良好的降解效果。降解反应符合一级反应动力学。
Cuprous oxide was prepared by hydrolyzation of CuCl and was tokened by TEM and XRD. p-nitrophenol was used to examine the photocatalyst in the artificial sunlight. The results indicate that cuprous oxide has high photoactivity and the degradation of p-nitrophenol solution of 22.4 mg/L is completed in 8 h under the irradiation of visible light. The degradation is first-order reaction.
