金团簇电催化二氧化碳还原反应的研究进展

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.
