Herein, we assess the application of copper(II) phthalocyanine (CuPc) in CO<sub>2</sub>RR as a model catalyst with definite local configurations, by employing <i>operando</i> X-ray spectroscopy under a three-electrode H-type cell (H-cell) and a gas-phase electrolyzer (flow-cell) to simulate the varying conditions of the mass transfer rate during CO<sub>2</sub>RR. High-energy resolution fluorescence detected X-ray absorption fine structure (HERFD-XAFS) spectroscopy and routine XAFS were used to precisely identify changes of both electronic and atomic structures among the active sites during CO<sub>2</sub>RR reactions, and the inverse relationship between the working current density and the reduced cluster size of the copper species was quantitatively depicted. Density functional theory (DFT) calculations indicated that the mass transfer rate was the major determinant of the local CO<sub>2</sub> concentration, which in turn affected the structural evolution of catalyst. In combination with <i>in-situ</i> synchrotron-radiation infrared adsorption spectroscopy (SR-IRAS), the size effect of Cu particles on the reaction kinetics of CO<sub>2</sub>RR was revealed. This work not only offers a comprehensive view at the atomic scale towards the rational design of advanced devices with high mass transfer rates, but also emphasizes the advances of <i>operando</i> high-energy resolution spectroscopic characterizations to fully understand dynamic structural changes and reaction mechanisms of CO<sub>2</sub>RR.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":772,"journal":{"name":"Science China Chemistry","volume":"68 5","pages":"2044 - 2050"},"PeriodicalIF":10.4,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
