MOF-based electrocatalysts for high-efficiency CO2 conversion: structure, performance, and perspectives

Electroreduction of CO2 to produce chemicals and fuels is recognized as a promising technology to reduce greenhouse gas emissions, especially by using renewable energy. In doing so, it is possible to achieve net-zero or negative emissions. A catalyst, however, is needed to facilitate the electroreduction of CO2 under ambient conditions. Recently, metal organic frameworks (MOFs) and their derivatives have gained growing attention in materials research due largely to their high surface area, unique local chemical structures, and extraordinary properties. MOF-based electrocatalysts are of particular interest for CO¬2 conversion with high activity, selectivity, and stability. The intent of this article is to provide an overview of the structures and performances of these electrocatalysts, as well as the perspectives and future trends in this field.
