摘要

研究了过渡金属salen配合物（Co、Ni、Cu）在零间隙电解槽中作为Co 2 - Co电还原的预催化剂。性能在很大程度上取决于金属选择和电极特性。XPS, UV-Vis，与简单金属盐的比较，以及rhee - zge半电池的设置，揭示了预催化剂分解和分子电催化剂多相化的方法。

Integrating Salen Complexes into Gas Diffusion Electrodes for CO2 Electroreduction: Considerations for Employing Molecular Precatalysts in Heterogeneous Electrolyzers

Transition metal salen complexes (Co, Ni, Cu) are studied as precatalysts for CO₂-to-CO electroreduction in zero-gap electrolyzers. Performance depends strongly on metal choice and electrode characteristics. XPS, UV-Vis, comparisons to simple metal salts, and a RHE-ZGE half-cell setup shed light on precatalyst decomposition and inform methodologies for molecular electrocatalyst heterogenization.
