摘要
以氯氧化锆和硝酸镍为反应物,采用共沉淀法制备纳米NiO/ZrO_(2)复合光催化剂,通过XRD、SEM、EDS表征催化剂的微观特性;考察Ni添加量、不同光源、催化剂用量、反应时间对亚甲基蓝(MB)降解效果的影响,并研究吸附过程的动力学。结果表明,当Ni添加量为15%,采用模拟太阳光源,反应时间为2.5 h,催化剂用量为0.6 g/L时,纳米NiO/ZrO_(2)复合光催化剂的降解效果较好;催化剂对MB的光催化降解反应符合一级动力学方程,反应速率常数为1.53 h^(-1)。
Using ZrOCl_(2)·8H_(2)O and Ni(NO_(3))_(2)·6H_(2)O as reactants,the nano-sized NiO/ZrO_(2) photocatalyst was prepared by co-precipitation method,and characterized by XRD,SEM and EDS.The effects of Ni addition,different light sources,amount of catalyst and reaction time on degradation effect of methylene blue(MB) were studied.The results showed that the degradation effect of nano-sized NiO/ZrO_(2) photocatalyst was better when the amount of Ni was 15%,simulated solar light source was adopted,the reaction time was 2.5h and the amount of catalyst was 0.6 g/L.The photocatalytic degradation of MB by the catalyst conforms to the first-order kinetic equation,and the reaction rate constant was 1.53 h^(-1).
