Reticular materials for electrochemical reduction of CO2

Abstract Catalytic conversion of excessively released greenhouse gas CO2 faces grand challenges in terms of efficiency, selectivity, and stability. Reticular chemistry holds promises for the rational design of framework-based electrocatalysts crossing molecule-material level. We highlight the achievements in tailoring electronic structure and mass transport properties of CO2 in framework materials, which have shown promising electrocatalytic CO2 reduction performance. We also outline the challenges in the fundamental understanding of electrocatalytic reduction of CO2 on framework materials, as well as heading to industrial utilization.
