Catalyst Aggregation Matters for Immobilized Molecular CO2RR Electrocatalysts

Here, we detail how the catalytic behavior of immobilized molecular electrocatalysts for the CO2 reduction reaction (CO2RR) can be impacted by catalyst aggregation. Operando Raman spectroscopy was used to study the CO2RR mediated by a layer of cobalt phthalocyanine (CoPc) immobilized on the cathode of an electrochemical flow reactor. We demonstrate that during electrolysis, the oxidation state of CoPc in the catalyst layer is dependent upon the degree of catalyst aggregation.

Solar driven CO2 reduction: from materials to devices

Solar-driven CO2 reduction for the production of fuels and chemicals is a promising technology for achieving carbon neutrality. Photocatalytic CO2 reduction, photoelectrochemical CO2 reduction and photovoltaic-electrochemical CO2 reduction, are three main approaches for solar-driven CO2 reduction that have attracted a lot of interest in both the academic and industrial communities.
