摘　　要：通过电化学方法来减少二氧化碳(CO_(2)),同时生产燃料和高附加值化学品,是一种克服全球变暖问题的有效策略,对于缓解能源和环境的双重压力具有重要的现实意义。由于CO_(2)稳定的分子结构,设计高选择性、高能效和低成本的电催化剂是关键。石墨烯及其衍生物因其独特且优异的物理、力学和电学性能,相对较低的成本,使其在CO_(2)电还原方面具有竞争力。此外,石墨烯基材料的表面可以通过使用不同的方法进行改性,包括掺杂、缺陷工程、构建复合结构和包覆形状。首先,本文综述了电化学CO_(2)还原的基本概念、评价标准,以及催化原理和过程。其次,简要介绍了石墨烯基催化剂的制备方法,并按照催化位点的类别,总结了石墨烯基催化剂近年来的研究进展。最后,对CO_(2)电还原技术未来发展方向进行了探讨与展望。The reduction of carbon dioxide(CO_(2))by electrochemical methods for the production of fuels and value-added chemicals is an effective strategy for overcoming the global warming problem.Due to the stable molecular structure of CO_(2),the design of highly selective,energy-efficient and cost-effective electrocatalysts is key.For this reason,graphene and its derivatives are competitive for CO_(2) electroreduction with their unique and excellent physical,mechanical and electrical properties and relatively low cost.In addition,the surface of graphene-based materials can be modified using different methods,including doping,defect engineering,production of composite structures and wrapped shapes.We first review the fundamental concepts and criteria for evaluating electrochemical CO_(2) reduction,as well as the catalytic principles and processes.Methods for preparing graphene-based catalysts are briefly introduced,and recent research on them is summarized according to the categories of the catalytic sites.Finally,the future development direction of CO_(2) electroreduction technology is discussed.
