In recent years, photocatalytic microbial fuel cells have gradually become a hot research topic in pollutant treatment, using either or indirectly the oxidation of organic pollutants by catalytic materials under light and the biodegradation and mineralization of various components in wastewater by microorganisms, or through the generation of electricity by the microbial fuel cell (MFC) system to promote the photogeneration and separation of electrons and holes by the catalytic materials of the photocatalytic cell (PC) system. This study aims to provide new ideas for the development of environmentally friendly wastewater treatment technologies by investigating the use of photocatalytic cells for the efficient degradation and resource utilization of target pollutants. This study aims to raise awareness of the use of photocatalytic microbial fuel cells for pollutant degradation by providing an overview of the practical status of photocatalytic microbial fuel cells. This is achieved by reviewing the key cathode development, production capacity, and progress in the degradation of pollutants in photocatalytic microbial fuel cells. The issues facing future developments are also discussed in terms of how photocatalytic microbial fuel cells work and how they degrade pollutants. This study shows that photocatalytic microbial fuel cells are beneficial for achieving renewable energy (bioenergy, photovoltaic, etc.) capacity and dealing with environmental pollution and that this is a novel technology that deserves to be promoted to achieve the current dual carbon targets.
近年来，光催化微生物燃料电池逐渐成为污染物处理领域的研究热点，它利用催化材料在光照下直接或间接氧化有机污染物，以及微生物对废水中各种成分的生物降解和矿化作用，或者通过微生物燃料电池（MFC）系统发电来促进光催化电池（PC）系统的催化材料产生光生电子和空穴并使其分离。本研究旨在通过研究光催化电池对目标污染物的高效降解和资源利用，为开发环保型废水处理技术提供新思路。本研究旨在通过概述光催化微生物燃料电池的实际应用状况，提高人们对其用于污染物降解的认识。这是通过回顾光催化微生物燃料电池中关键阴极的发展、产能以及污染物降解方面的进展来实现的。还从光催化微生物燃料电池的工作方式及其如何降解污染物的角度讨论了未来发展面临的问题。本研究表明，光催化微生物燃料电池有利于实现可再生能源（生物能源、光伏能源等）产能并应对环境污染，这是一项值得推广以实现当前双碳目标的新技术。
