Cu is one of the interesting CO2 reduction reaction catalysts due to its unique capability to produce many of the hydrocarbon chemicals in addition to H2, and the nanostructures of the Cu-based electrocatalyst significantly affect the product selectivity for C2+ over C1 chemicals. Although material engineering strategies have aimed at the design of a selective C2+-producing catalyst, the role of the fundamental descriptor allowing control of the desired pathway is not yet well-understood. In this context, reliable guidelines for highly selective reactions require understanding the catalyst material and the reaction pathways. Both of a H-cell and gas-diffusion-electrode (GDE) based membrane electrode assembly (MEA) cells have shown the enhanced ethylene selectivity with Cu nanoparticles prepared by oxide forms. In this talk, the recent studies on Cu catalysts will be discussed from the point of fundamental mechanism understanding to the MEA device applications. |
