Abstract: Bi2WO6,Bi2MoO6,BiPW12O40 and BiPMo12O40 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 temperature and different substrates was explored.The best degradation of RhB (100 mL 4 mg/L) achieved 98.1% over the unbaked Bi2WO6 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.

Key words: photocatalysis, bismuthic catalyst, RhB, methyl orange, methylthionine chloride, organic pollutants
