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

Abstract

Electroreduction of CO₂ to produce chemicals and fuels is recognized as a promising technology to reduce greenhouse gas emissions, particularly 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 CO₂ 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.
