Photocoupled electroreduction of CO2 over photosensitizer decorated covalent organic frameworks

Electrocatalytic CO2 reduction reaction (CO2RR) is thought to be an ecologically favorable technique for using CO2 as a cheap and abundant C1 feedstock for the production of value-added chemicals such as CO. However, the thermodynamically stable nature of the CO2 molecule featuring high C=O bond energy frequently leads to sluggish kinetics of CO2→CO and high energy inputs.
