摘要
Photocatalyses such as hydrogen generation from water splitting or degrading organic contaminant on photocatalysts under solar light is promising in solving current energy and environmental issues. Bismuth ferrite (BiFeO3) is a newly emerging photocatalytic material in parallel with the widely used TiO2-based materials, and the narrow band gap (2.1-2.7 eV) of BiFeO3-based materials (BFO) makes the visible-light photocatalysis such as hydrogen generation by water splitting become possible. In this review, BFO with different particle sizes and morphologies prepared by various preparation methods such as sol-gel, hydrothermal and microwave hydrothermal was summarized and the effects of particle size and/or morphology on the photocatalytic activity were discussed. The effects of the addition of dopants and formation of hetero-junction on the BFO photocatalytic activity were also evaluated. The examples of H-2 production and degradation of organic pollutants by using BFO as the photocatalysts were given in the end and the future work about the photocatalyses of BFO material is also suggested.
