Recent advances and future perspectives of metal-organic frameworks as efficient electrocatalysts for CO2 reduction

Abstract

The conversion of carbon dioxide (CO2) to the reduced chemical compounds offers substantial environmental benefits through minimizing the emission of greenhouse gas and fostering sustainable practices. Recently, the unique properties of metal-organic frameworks (MOFs) make them attractive candidates for electrocatalytic CO2 reduction reaction (CO2RR), providing many opportunities to develop efficient, selective, and environmentally sustainable processes for mitigating CO2 emissions and utilizing CO2 as a valuable raw material for the synthesis of fuels and chemicals. Here, the recent advances in MOFs as efficient catalysts for electrocatalytic CO2RR are summarized. The detailed characteristics, electrocatalytic mechanisms, and practical approaches for improving the electrocatalytic efficiency, selectivity, and durability of MOFs under realistic reaction conditions are also clarified. Furthermore, the outlooks on the prospects of MOF-based electrocatalysts in CO2RR are provided.
