摘　　要：水污染已成为当今社会最主要的环境问题之一,采取有效手段来解决水污染问题已迫在眉睫。近年来,光催化氧化技术作为一种新兴治理技术引起了人们广泛的兴趣。尽管半导体催化剂已在有机污染物治理方面表现出优异的特性,但仍有很多难题亟待解决。铁酸铋由于具有较窄的禁带宽度和较好的可见光响应能力,被认为是半导体催化剂的候选材料之一。因此,研究制备铁酸铋纳米结构和铁酸铋基的复合物催化剂,有效提升其光催化活性,具有潜在的实际应用价值。本文总结了作者所在课题组近年来在铁酸铋复合材料制备及在可见光催化中应用的研究进展。Nowadays, water pollution is one major of the environmental problems and it is very urgent to solve such problems by various means. In recent years, photocatalytic oxidation technology attracts extensive concerns, which has become a new treatment technology. Although, semiconductor photocatalysts have exhibited excellent performance in the treatment of organic pollutant, there still exits many problems to be solved. Bi Fe O3 with a narrow band gap is considered to be the promising candidate as semiconductor photocatalyst in the visible light range. Therefore, it is very important to conduct critical studies on the preparation of Bi FeO3-based composite photocatalysts with high photocatalytic activity. This paper gives a brief review on the research progress on bismuth ferrite nanocomposites photocatalyst in our research group in recent years.
