Harmonized Physical and Electrochemical Process Design for Densely Dispersed Cu Catalysts on Cu₂O Absorbers for Efficient Photoelectrochemical CO₂ Reduction Reaction (Adv. Energy Mater. 10/2024)

CO2 Reduction Reaction In article number 2304239,Hyung Koun Cho and co-workers present a novel co-catalyst formationmechanism in a photoelectrochemical cell, termed the harmonized physical and electrochemical formation process. This concept is derived from the selective photoreduction process. Furthermore, the co-catalyst formation approach, prepared through a two-step process, establishes a dominant pathway for the CO2 reduction reaction, significantly suppressing photocorrosion and improving the charge kinetics of solar-generated carriers.
