摘要
本文利用水热合成法制备SO4^2-/Ni2O3-TiO2光催化剂。样品结构经过测试手段进行了表征,结果表明,该光催化剂主要由锐钛矿TiO2和立方体的Ni2O3组成,SO4^2-既有螯合双配位方式又有桥式双配位的形式结合在Ni2O3-TiO2表面,并在Ti与Ni的摩尔比为1:0.05时的光催化剂具有更高的脱色效率,当亚甲基蓝初始浓度为2.5mg·L^-1和催化剂用量为0.1g时,脱色效率可达98.65%。
SO4^2-/NI2O3-TIO2 photocatalyst was prepared by hydrothermal method.The results show that the photocatalyst is mainly composed of anatase TIO2 and cubic Ni2O3,and SO4^2-is bound to Ni2O3-TiO2 surface in the form of both chelated double coordination and bridged double coordination,when the molar ratio of Ti to Ni was 1:0.05,the decolorization efficiency of photocatalyst was 98.65%when the initial concentration of Methylene blue was 2.5 mg·L^-1 and the dosage of catalyst was 0.1 g.
