摘要
The reduction of carbon dioxide (CO2) 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 CO2, the design of highly selective, energy-efficient and cost-effective electrocatalysts is key. For this reason, graphene and its derivatives are competitive for CO2 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 CO2 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 CO2 electroreduction technology is discussed.
