Abstract

Converting carbon dioxide (CO2) into value-added chemicals is considered as a promising strategy to mitigate climate change. Among the various CO2 reduction techniques, electrochemical CO2 reduction (ECO2R) using renewable energy sources holds significant potential. Consequently, the design and development of electrocatalysts capable of offering both high performance and cost-effectiveness hold the potential to expedite reaction kinetics and facilitate widespread industrial adoption. In recent years, abundant copper sulfide (Cu/S)-based nanomaterials among various metal–chalcogenides have attracted extensive research interest due to their semiconductivity and low toxicity, enabling them to be used in a wide range of applications in the ECO2R field. This review highlights the progress in engineered Cu/S-based nanomaterials for ECO2R reactions and elaborates on the correlations between engineering strategies, catalytic activity, and reaction pathways. This paper also summarises the controllable synthesis methods for fabricating various state-of-the-art Cu/S-based structures and outlines their possible implementation as electrocatalysts for CO2 reduction. Finally, challenges and prospects are presented for the future development and practical applications of Cu/S-based catalysts for ECO2R to value-added chemicals.

用于将二氧化碳电化学还原为甲酸及其他物质的硫化铜相关催化剂的可控合成:综述
将二氧化碳(CO2)转化为高附加值的化学品被认为是减缓气候变化的一项有前途的战略。在各种二氧化碳还原技术中,利用可再生能源进行电化学二氧化碳还原(ERCO2)具有巨大潜力。因此,设计和开发既能提供高性能又具有成本效益的电催化剂,有可能加快反应动力学,促进工业广泛采用。近年来,在各种金属钙化物中,与硫化铜(Cu/S)相关的丰富纳米材料因其半导体和低毒特性而受到广泛的研究关注,使其能够广泛应用于ERCO2领域。本综述重点介绍了用于ERCO2 反应的工程化 Cu/S 相关纳米材料的研究进展,并详细阐述了工程化策略、催化活性和反应途径之间的相互关系。论文还总结了制造各种最先进的 Cu/S 相助结构的可控合成方法,并概述了将其作为电催化剂用于二氧化碳还原的可能性。最后,还介绍了用于 ECO2R 的 Cu/S 相助催化剂在未来发展和实际应用方面的挑战和前景,以及如何将其转化为高附加值化学品。
