如今，当我们面临水传播疾病的大规模流行时，必须找到有效的废水处理技术。针对传统处理方法产生大量污泥等缺点，光催化分解似乎是处理工业废水，特别是偶氮染料和其他有机污染物的有效技术。这种引人入胜的技术解决了人类的两个问题，水危机和环境问题。就容量而言，铁氧体铋纳米团簇由于其可接受的频率范围、宽的可见光吸收和良好的稳定性，似乎是一种用于降解各种染料的有效半导体材料。众所周知，当对铁酸铋薄片进行改性时，这些特性会在更大程度上增加。本综述详细总结了与使用传统方法相关的局限性、光催化剂降解的新兴技术、光催化剂的钙钛矿结构、降解机制和铁酸铋纳米粒子的改性，以提高光催化性能和表征研究。基本上，修改涉及掺杂技术，即，结合支撑材料、制备异质结和产生氧空位。此外，还提出了未来的挑战和前景，以关注需要研究人员特别感兴趣的领域。因此，本综述旨在通过总结当前的研究状态并提供有关处理铋环境的有效技术的信息，来提供关于铁酸铋光催化剂的概述和知识。

Bismuth ferrite (BiFeO3) perovskite-based advanced nanomaterials with state-of-the-art photocatalytic performance in water clean-up

Nowadays, as we face a massive epidemic of water-borne diseases, it is essential to find effective techniques for treating wastewater. Against the drawbacks of conventional treatment methods such as the generation of a lot of sludge, photocatalytic decomposition appears to be an effective technology for the treatment of water against industrial wastewater, especially azo dyes and other organic pollutants. This fascinating technique solves two problems of humanity, water crises as well as environmental problems. In terms of capacities, bismuth ferrite nanoclusters appear to be an effective semiconductor material for the degradation of a wide range of dyes due to their acceptable frequency range, wide visible light absorption, and good stability. These properties are known to increase to a greater extent when thin sheets of bismuth ferrite are modified. This review summarizes in detail the limitations associated with the use of conventional methods, emerging techniques for photocatalyst degradation, perovskite structure of photocatalysts, degradation mechanisms, and modifications of bismuth ferrite nanoparticles to improve photocatalytic performance and characterization studies. Basically, the modification involves a doping technique, i.e., combining support materials, preparing heterojunctions, and creating oxygen vacancies. In addition, future challenges and prospects are presented to focus on an area that requires the special interest of researchers. Therefore, this review aims to provide an overview and contribute to knowledge on bismuth ferrite photocatalysts by summarizing the current state of research and providing information on efficient techniques to handle bismuth environments.
