| 摘要: 通过直接搅拌法制备了2种CuBi双钙钛矿材料修饰的Cu金属有机骨架(CuBi@Cu-MOF)，并系统评估了2种材料作为电催化剂在碱性体系中对CO2还原反应产物的选择性和法拉第效率(FE)。结果表明，表面改性后的CuBi@Cu-MOF催化剂表现出明显提升的HCOOH选择性，其对应的最高FE可达56%，优于Cu-MOF催化剂本身的FE (15%)。研究结果显示，表面改性降低了电荷转移阻力，增加了活性位点数量，从而提高了电催化活性。 |

| Abstract: Two kinds of CuBi double perovskite modified Cu-metal-organic framework (CuBi@Cu-MOF) were prepared using a simple stirring method. The product selectivity and Faraday efficiency (FE) of the two composite materials as electrocatalysts for CO2 reduction were systematically evaluated in an alkaline system. The results demonstrated that CuBi@Cu-MOFs exhibited significantly enhanced HCOOH selectivity, the maximum FE of CuBi-MOF reached 56% which was better than the FE of Cu MOF catalyst itself (15%). The surface modification reduces the charge transfer resistance and increases the active sites, thus improving the electrocatalytic performance. |
