摘要:
铋系半导体材料是一类重要的光催化材料,而碘氧化铋是其中带隙较窄的少数几种之一,其光吸收波长范围几乎覆盖全部可见光,具有较强的可见光响应性能。然而,这一优势没有得到充分利用,块体碘氧化铋的光催化性能并不理想,需要通过改性,使其光催化性能得到增强。由于碘氧化铋的结构在铋系光催化材料中非常具有代表性,几乎所有铋系光催化材料的改性增强策略都能用于碘氧化铋的改性,故其相关研究对于铋系光催化材料研究有较高的参考价值,引起了许多研究者的关注。为此,本文对近年来围绕碘氧化铋结构调控、形貌调控、复合和表面修饰等方面的改性研究进行综述,分析和总结改性处理在促进光吸收、载流子传输与分离、调控带隙结构等方面的作用机制,为新型可见光光催化材料的研究提供借鉴。
Abstract:
Bismuth-based semiconductors are an important family of photocatalysts, in which bismuth oxyiodide is one of those with narrow band gap and excellent visible light response. However, the photocatalytic activity of bulk bismuth oxyiodide is usually not satisfactory, and need to be improved by various strategies. The layered structure of bismuth oxyiodide is very typical in Bi-based photocatalysts, and almost all strategies for enhancing the photocatalytic performance of Bi-based photocatalysts are adaptable for bismuth oxyiodide. Hence the modification of bismuth oxyiodide is of significant referential importance for Bi-based photocatalysts, and has attracted numerous attentions. Herein, we overview the recent advances on the modification of bismuth oxyiodide in this paper, by using the strategies such as structure and morphology control, composite construction and surface modification. The relevant mechanism on promoting the light absorption, charge carrier migration and separation, and tuning the band structure were also summarized. It is believed that this review will provide a guidance for the development of highly efficient visible-light-driven photocatalysts.
