Converting solar energy into fuels/chemicals through photochemical approaches holds significant promise for addressing global energy demands. Currently, semiconductor photocatalysis combined with redox techniques has been intensively researched in pollutant degradation and secondary energy generation owing to its dual advantages of oxidizability and reducibility; however, challenges remain, particularly with improving conversion efficiency. Since graphene's initial introduction in 2004, three-dimensional (3D) graphene-based photocatalysts have garnered considerable attention due to their exceptional properties, such as their large specific surface area, abundant pore structure, diverse surface chemistry, adjustable band gap, and high electrical conductivity. Herein, this review provides an in-depth analysis of the commonly used photocatalysts based on 3D graphene, outlining their construction strategies and recent applications in photocatalytic degradation of organic pollutants, H evolution, and CO reduction. Additionally, the paper explores the multifaceted roles that 3D graphene plays in enhancing photocatalytic performance. By offering a comprehensive overview, we hope to highlight the potential of 3D graphene as an environmentally beneficial material and to inspire the development of more efficient, versatile graphene-based aerogel photocatalysts for future applications.
通过光化学方法将太阳能转化为燃料/化学品在满足全球能源需求方面具有重大前景。目前，半导体光催化与氧化还原技术相结合，因其具有氧化性和还原性的双重优势，在污染物降解和二次能源生成方面受到了广泛研究；然而，挑战依然存在，尤其是在提高转化效率方面。自2004年石墨烯首次被引入以来，基于三维（3D）石墨烯的光催化剂因其优异的性能，如大比表面积、丰富的孔结构、多样的表面化学性质、可调节的带隙和高电导率，而备受关注。在此，本综述对常用的基于3D石墨烯的光催化剂进行了深入分析，概述了它们的构建策略以及在光催化降解有机污染物、析氢和CO还原方面的最新应用。此外，本文还探讨了3D石墨烯在提高光催化性能方面所起的多方面作用。通过提供全面的概述，我们希望突出3D石墨烯作为一种对环境有益的材料的潜力，并激发开发更高效、多功能的基于石墨烯的气凝胶光催化剂以供未来应用。
