当前工业发展导致了严重的能源和环境危机,光催化为这一难题提供了有效的解决方案。然而在实际应用中,传统氧化物光催化剂宽的带隙限制了它的可见光吸收,于是窄带隙光催化剂成为了研究的热点。其中铋系光催化剂以其高的可见光光催化活性引起了人们的广泛关注。因此本文介绍了铋系光催化剂的种类、制备、形貌、复合、性能等方面的研究现状,并展望了含铋可见光催化剂发展前景。
Photocatalysis is considered to be an effective solution for the current energy and environmental crises caused by industrial development. However, the practical application of conventional oxide photocatalysts is restricted by poor visible light adsorption because of their wide band gaps. The study of photocatalysts with a narrow band gap is thus a hot topic. Among oxide photocatalysts, Bi-based photocatalysts have attracted much interest because of their high visible light photocatalytic activity. This review summarizes recent advances into the type, preparation method, morphology control, composite construction, and properties of Bi-based photocatalysts. Finally, this review ends with a discussion on the future development of Bi-based photocatalysts in this exciting research area.
