Abstract
BiFeO3 (BFO) is considered to be a potential visible light photocatalytic material for organic degradation due to its narrow band gap. In this work, the BFO with smaller band gap and better photocatalytic performance was prepared by thermal decomposition of we prepared smaller band gap and better photocatalytic performance BFO by thermal decomposition of MOFs precursor Bi[Fe (CN)6]·5H2O. Among them, BFO‐0.5 has the best photocatalytic activity, which the photocatalytic degradation rate of methyl orange (MO) aqueous solution is 98.1% within 60 minutes. The photocatalytic activity is almost unchanged after four cycles of use. The enhanced photocatalytic activity of BFO could be attributed to the enhanced optical absorption and smaller particles. It may be conducive to design more efficient photocatalysts for photocatalytic degradation of organic dyes.
