钨／钼／磷钨／磷钼酸铋盐的催化性能
Catalytic Performance of Tungstate/Molybdate/Phosphotungstic/Phosphomolybdate Acid Bismuth Salt
摘要
Abstract
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 .关键词
