Abstract

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.

石墨烯基二氧化碳还原电催化剂:综述
利用电化学方法还原二氧化碳(CO2)以生产燃料和高附加值化学品,是解决全球变暖问题的有效策略。由于二氧化碳分子结构稳定,因此设计高选择性、高能效和高成本效益的电催化剂至关重要。因此,石墨烯及其衍生物以其独特而优异的物理、机械和电气性能以及相对较低的成本,在二氧化碳电还原方面具有很强的竞争力。此外,石墨烯基材料的表面可以通过不同的方法进行改性,包括掺杂、缺陷工程、生产复合结构和包裹形状。我们首先回顾了评估电化学二氧化碳还原的基本概念和标准,以及催化原理和过程。简要介绍了制备石墨烯基催化剂的方法,并根据催化位点的类别总结了近期的相关研究。最后,讨论了二氧化碳电还原技术的未来发展方向。

期刊介绍: New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
