The global energy shortage and environmental degradation are two major issues of concern in today's society. The production of renewable energy and the treatment of pollutants are currently the mainstream research directions in the field of photocatalysis. In addition, over the last decade or so, graphene (GR) has been widely used in photocatalysis due to its unique physical and chemical properties, such as its large light-absorption range, high adsorption capacity, large specific surface area, and excellent electronic conductivity. Here, we first introduce the unique properties of graphene, such as its high specific surface area, chemical stability, etc. Then, the basic principles of photocatalytic hydrolysis, pollutant degradation, and the photocatalytic reduction of CO are summarized. We then give an overview of the optimization strategies for graphene-based photocatalysis and the latest advances in its application. Finally, we present challenges and perspectives for graphene-based applications in this field in light of recent developments.
全球能源短缺和环境恶化是当今社会关注的两个主要问题。可再生能源的生产和污染物的处理是目前光催化领域的主流研究方向。此外，在过去十年左右的时间里，石墨烯（GR）因其独特的物理和化学性质，如光吸收范围大、吸附能力高、比表面积大以及优异的电子导电性，而被广泛应用于光催化领域。在此，我们首先介绍石墨烯的独特性质，如高比表面积、化学稳定性等。然后，总结光催化水解、污染物降解以及CO光催化还原的基本原理。接着，概述基于石墨烯的光催化的优化策略及其应用的最新进展。最后，根据近期的发展情况，阐述基于石墨烯的应用在该领域面临的挑战和前景。
