Electrochemical CO2 reduction to value-added chemicals has been highlighted as a sustainable carbon cycle technology. Recent material engineering strategies coupled with device designs have made noticeable progress to achieve high conversion rate. Especially, defective structures of the nanoparticle catalysts have shown high intrinsic activity for CO2RR over hydrogen evolution reaction (HER), and thus high product selectivity. Although nanostructures are advantageous to have high activity and high surface area, 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 and stability 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 CO2RR with nanoparticles catalysts. In this talk, the recent studies on nanoparticle catalysts will be discussed from the point of fundamental mechanism and durability understanding to the MEA device applications.
