摘要

以Bi(NO_3)_3·5H_2O、Na_2W_4·2H_2O和I_2O_5为原料,使用水热法合成复合催化剂Bi IO_4/Bi_2WO_6。用甲基橙作为污染物并以250 W金卤灯模拟太阳光光源,研究复合催化剂的催化性能,结果表明复合催化剂较纯的钨酸铋和碘酸铋催化降解甲基橙的性能有所提高,可达93.66%。同时利用固体紫外-可见漫反射测试(UV-vis DRS)、X射线光电子能谱(XPS),对合成样品进行表征,研究所得Bi IO_4/Bi_2WO_6的结构和性能。
        With Bi(NO_3)_3·5H_2O、Na_2WO_4·2H_2O and I_2O_5as raw materials,the composite catalysts BiIO_4/Bi_2WO_6were synthesized by hydrothermal method.Photocatalytic activity of the composite catalyst was studied by using methyl orange as contaminants and simulating 250 W metal halide lamp as the sun light.The results showed that the catalytic properties of composite catalyst compound for degradation of methyl orange had increased to 93.66%compared with Bi_2WO_6and BiIO_4.Then the synthesized samples were characterized via UV-visible diffuse-reflectance spectrum(UV-vis DRS)and X-ray photoelectron spectroscopy(XPS).
