SnO_2 as co-catalyst for enhanced visible light photocatalytic activity of Bi_2MoO_6

摘要

Exploring visible light active semiconductor photocatalysts is one of greatly significant issues. We show herewith the Bi2MoO6/SnO2 hybrid photocatalysts meet the requirement for degradation of organic contaminant. The Bi2MoO6/SnO2 displays better visible light catalytic activity than that of Bi2MoO6 center dot SnO2 as co-catalyst can provide more active sites as well as transfer and restrain the charge recombination, leading to the enhancement of catalytic activity. 30 wt.% SnO2 emersions can degrade 90% for nitrobenzene and 97% for Rhodamine under visible light irradiation.
