摘要
二氧化碳电还原反应(CO_(2)RR)在改善能源利用方式、实现可持续碳循环以及生产高附加值液体燃料和化学品等方面具有广阔的应用前景,近年来受到广泛关注.有机配体保护的金团簇具有确定的晶体结构,其不同的尺寸、配体及组成可以有效调控氧化还原电位,作为一种独特的模型催化剂,为探索原子水平的CO_(2)RR反应机理提供了新机遇.本文综合评述了纯金团簇和异金属原子掺杂的金团簇催化CO_(2)RR的研究进展,包括金团簇的电荷、尺寸、配体以及掺杂对CO_(2)RR性能的影响,重点讨论了CO_(2)RR的反应机理,总结了金团簇在CO_(2)RR中所面临的挑战,并展望了金团簇在CO_(2)RR中未来的研究方向和发展前景.
Recently,the electrocatalytic CO_(2) reduction reaction(CO_(2)RR)has attracted great attention because its wide application prospects in improving energy utilization,realizing sustainable carbon recycle and producing high value-added liquid fuels and chemicals.Atomically precise gold clusters protected by organic ligands show many advantages for electrocatalysis due to the well-defined structures.The redox potentials can be tuned by their cluster size,ligand,and composition of these clusters.Acted as ideal model catalysts,the gold clusters provide a new opportunity to explore the reaction mechanism of CO_(2)RR at the atomic level.In this review,the research progress of CO_(2)RR catalyzed by gold clusters is surveyed,including the effects of the charge,size,ligand and doping of gold nanoclusters on the performances of CO_(2)RR.Particularly,the reaction mechanism of CO_(2)RR is discussed in details.Besides,the challenges and prospects of gold nanoclusters in CO_(2)RR are also presented.
