Toward High‐Performance CO2‐to‐C2 Electroreduction via Linker Tuning on MOF‐Derived Catalysts

Copper (Cu)‐based metal–organic frameworks (MOFs) and MOF‐derived catalysts are well studied for electroreduction of carbon dioxide (CO2); however, the effects of organic linkers for the selectivity of CO2 reduction are still unrevealed. Here, a series of Cu‐based MOF‐derived catalysts is investigated with different organic linkers appended, named X‐Cu‐BDC (BDC = 1,4‐benzenedicarboxylic acid, X = NH2, OH, H, F, and 2F). It is found that the linkers affect the faradaic efficiency (FE) for C2 products with an order of NH2
