摘　　要：以硝酸银、磷酸氢二钠为主要原料,采用水热法制备了高催化活性Ni^(2+)离子掺杂磷酸银(Ag_3PO_4)光催化剂,通过XRD、SEM、FT-IR、UV-Vis、DRS和PL等对其进行表征。以亚甲基蓝溶液为模拟废液进行光催化降解实验来评价磷酸银光催化活性,探讨了掺杂不同摩尔质量Ni^(2+)离子对产物催化性能的影响。结果表明,产物为立方晶相磷酸银纳米微球。0.08g试样经过可见光催化降解浓度为8mg/L的亚甲基蓝溶液(200mL),催化降解6min后,掺杂摩尔分数为2%Ni^(2+)的Ag_3PO_4样品降解率为94.52%,3次循环降解后,降解率达仍达到89.76%。The Ni^2＋ doped Ag_3PO_4 photocatalyst with good activity was synthesized by hydrothermal solutions using AgNO_3 and Na_2HPO_4 as raw materials,and characterized by XRD,SEM,FT-IR,UV-Vis,DRS and PL.The photocatalytic activity of Ag_3PO_4 doped Ni^2＋with different molar mass was tested by the photocatalytic degradation of methylene blue aqueous solution.The results showed that the synthesized samples were pure cubic Ag_3PO_4 nano-microspheres.The degradation rate of 0.08 g 2%（molar concentration）Ni^2＋-doped Ag_3PO_4 can reached 94.52% as the initial methylene blue was 8mg/L（200mL）,illumination time was 6min,and 89.76% after cycled for three times.
