Dye-sensitized photoelectrochemical cell combining a MOF catalyst and cobaltocene CoCpCp* as redox mediator for CO2 reduction

Abstract

Integration of a photocathode, CoCpCp*, and a heterogenized rhenium catalyst within PCN-777 provides stable photocurrent and CO as the product of photo-driven CO2 reduction. Control experiments confirm the role of CoCpCp* as redox mediator. This proof-of-concept study illustrates the feasibility of using MOF-embedded molecular catalysts in DS-PEC systems.
