Abstract:

Recently, the electrocatalytic CO2 reduction reaction(CO2RR) 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 CO2RR at the atomic level. In this review, the research progress of CO2RR catalyzed by gold clusters is surveyed, including the effects of the charge, size, ligand and doping of gold nanoclusters on the performances of CO2RR. Particularly, the reaction mechanism of CO2RR is discussed in details. Besides, the challenges and prospects of gold nanoclusters in CO2RR are also presented.
