摘要
世界经济迅速发展导致的环境污染和能源危机成为全球共同面对的威胁与挑战,光催化技术为该问题提供了高效的解决方案.氟氧化铋(BiOF)具有特殊的层状结构、低毒性、高稳定性、丰富的可调控性和良好的光催化性等优点,成为光催化研究领域的重要材料.然而BiOF带隙较大,导致其光生载流子易复合且电荷转移率低,因此寻求新的合成方式及改性修饰方法对提高BiOF光催化性能具有重要研究意义.本文介绍了近年来BiOF光催化剂的制备方法、改性策略、反应机制等方面的研究现状,综述分析其在降解污染物、CO2还原、电极与电池、纳米铝热剂等环境能源领域的应用,并对该类材料未来的发展与可能面临的挑战做出展望,旨在为开发新型高效的BiOF光催化剂提供理论借鉴与技术支撑.
Abstract
The rapid development of the world economy has led to environmental pollution and energy crisis,posing a global threat and challenge.Photocatalysis technology provides an efficient solution to address these issues.Bismuth oxyfluoride(BiOF)has attracted significant attention as an important material in the field of photocatalysis due to its unique layered structure,low toxicity,high stability,tunability,and excellent photo-catalytic performance.However,the wide bandgap of BiOF leads to easy recombination of photo-generated charge carriers and low charge transfer rate,thus it is of great research significance to seek new synthesis methods and modification techniques to improve the photocatalytic performance of BiOF.This paper introduces the preparation method,modification strategy and reaction mechanism in recent years.This review analyzes the applications of BiOF photocatalyst in the areas of pollutant degradation,CO2 reduction,electrodes and batteries,and nano-aluminum thermal agents in the field of environmental energy.It also provides prospects for the future development and challenges of such materials,aiming to provide theoretical guidance and technical support for the development of novel efficient BiOF photocatalyst.
