To achieve target product selectivity, it is essential to strategically manipulate the reaction pathway. Herein, we build Cu−Ag dual hetero-metal atom pair sites for photoreduction of 0.03% CO2 into methanol (CH3OH). In situ Fourier transform infrared spectroscopy is employed to probe the formation of the *CHO group, a critical intermediate during the synthesis of CH3OH, in the CO2 photoreduction on the CuAg/In2O3 nanosheets. Nevertheless, this critical intermediate is not detected under similar conditions on the In2O3 nanosheets. Additionally, theoretical calculations reveal that the energy barrier for the formation of *CHO intermediates (0.31 eV) is lower than that required for the desorption of *CO intermediates to produce carbon monoxide (0.57 eV) on the CuAg/In2O3 nanosheet slab. That suggests a pronounced selectivity toward the production of CH3OH. Consequently, the CuAg/In2O3 nanosheets realize photoreduction of 0.03% CO2 into CH3OH without any sacrificial agent, achieving a formation rate of 3.67 μmol g–1 h−1.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"127 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144736729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
