摘要(Abstract)：

采用水热合成法在Cu2(OH)PO4表面原位沉积Ni(OH)2,制备异质结型的复合光催化剂Cu2(OH)PO4/Ni(OH)2;利用X线粉末衍射仪(XRD)、紫外-可见漫反射光谱仪(UV-Vis-DRS)和扫描电子显微镜(SEM)等,对其相结构、光吸收性能和微观形貌进行表征.结果表明:该复合光催化剂具有良好的紫外光吸收特性,是一类新型的光催化剂.复合光催化剂在紫外光下可以有效降解亚甲基蓝(MB)溶液,当Cu2(OH)PO4与Ni(OH)2的摩尔比为0.2时,Cu2(OH)PO4/Ni(OH)2具有最大催化活性.根据光催化中加入不同活性物种牺牲剂的实验,推测该异质结型材料光催化过程中光生载流子的传输方向及活性物种.Cu2(OH)PO4/Ni(OH)2的催化活性增强主要归结为复合时在两者之间形成有效的异质结,结区的内建电场能够促进光生载流子的分离,同时·OH和h+在光催化降解过程中是主要的活性物种.
