Surface modified copper foam with cobalt phthalocyanine carbon nanotube hybrids for tuning CO2 reduction reaction products

Javier O Rivera-Reyes et al. Chem Commun (Camb). .

Abstract

The CO2 reduction reaction (CO2RR) is a feasible way to convert this greenhouse gas into molecules of industrial interest. Herein we present the modification of the Cu foam cathode using molecular catalyst hybrid from cobalt phthalocyanine (CoPc) to increase selectivity and stability towards CO2RR products in a flow cell setup.
