利用水热和共沉淀法合成了钨酸铋、钼酸铋、磷钨酸铋和磷钼酸铋4种铋系催化剂，通过红外光谱（I R ）、紫外光谱（UV‐vis）、荧光光谱（FL）、X‐ray粉末衍射（XRD）和扫描电镜（SEM ）等手段对所合成样品的形貌和性质进行表征．从制备条件、焙烧温度、不同降解底物等方面对4种催化剂的催化降解性能进行探究和对比，发现当钨酸铋催化剂中W与Bi物质的量之比为1∶2的未焙烧的催化剂催化降解4 mg／L的罗丹明B（RhB）的效果最佳，可达98．1％，并对甲基橙、亚甲基蓝等多种有机污染物有一定的催化降解效果；钨酸铋、钼酸铋催化剂也分别对 RhB、甲基橙、亚甲基蓝等有良好的催化效果；而磷钼酸铋对上述污染物催化降解效果较差．

Bi2 WO6 ,Bi2 MoO6 ,BiPW12 O40 and BiPMo12 O40 catalysts were synthesized by hydrothermal and co‐precipitation method and characterized by IR ,UV‐vis ,FL ,SEM and X‐ray power diffraction (XRD) . The relationship between catalytic performance of catalysts and preparation conditions ,calcination tem‐perature and different substrates was explored .The best degradation of RhB (100 mL 4 mg/L) achieved 98 .1% over the unbaked Bi2 WO6 with the W/Bi molar rate 1∶2 ,which also had certain catalytic effect for degrading methyl orange and methylthionine chloride .The tungstate bismuth and molybdate bismuth catalysts had a good catalytic effect for degrading RhB ,methyl orange and methylthionine chloride as well .The catalytic performance of phosphomolybdate bismuth was poorer .
