摘要
采用水热法制备了一系列金属离子掺杂的钨酸铋、钼酸铋、磷钼酸铋等含氧酸铋盐光催化材料,评价其在可见光下降解有机染料的光催化性能。详细考察了掺杂金属离子种类、掺杂量及有机染料种类对其光催化性能的影响。结果表明,0.5%Fe/Bi_2WO_6对罗丹明B的降解率最好,可达到98.3%。
A series of bismuth tungstate,bismuth molybdate,bismuth phosphomolybdate bismuth with different metal ions doped were prepared by hydrothermal method,and their photocatalytic activities were investigated via testing the degradation of organic dyes under visible light. The effects of doping metal ions,doping amount and kinds of organic dye on the photocatalytic performance were examined in detail. The results showed that the degradation rate of rhodamine B could be reached 98. 3% when the 0. 5% Fe/Bi2WO6 used as photocatalyst.
