| 摘 要： | 用CuCl水解法制备Cu2O粉末,用透射电镜(TEM)和X衍射(XRD)对Cu2O粒子进行了表征.在仿太阳光源的照射下,研究了Cu2O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8
h内,对硝基苯酚几乎完全降解.在催化剂用量为0.2 g时,对浓度为22.4 mg/L的200mL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.

| Abstract: | 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. |
