以CuSO4为原料,Ce(NO3)3为改性剂,水合肼为还原剂,制备了铈改性Cu2O复合物,用X射线衍射、X射线光电子能谱、傅里叶红外光谱、紫外-可见吸收光谱仪、荧光光谱对其结构进行了表征.以亚甲基蓝为目标化合物,评价了其可见光催化活性.结果表明,在40 W日光灯的照射下,20 mg/L亚甲基蓝溶液的3.5h降解率达到86.6%,其降解规律符合一级动力学方程.
Cu2O nanocomposite doped with Ce was prepared with CuSO4 as raw material,Ce (NO3) 4 as the modifier and hydrazine hydrate as reductant.The nanocomposite was characterized by XRD,XPS,UV-vis DRS,IR,and PL techniques.The Visible light photocatalytic activity of the nanocomposite was evaluated by methylene blue.The photocatalytic degradation rate of methylene blue with the nanocomposite is more than 86% after 3.5h.The degradation progress Comforms to the first order kinetics equation.
