Paper Title: Atomically tunable photo-assisted electrochemical oxidation process design for the decoration of ultimate-thin CuO on Cu2O photocathodes and their enhanced photoelectrochemical performances
Contents: Hydrogen energy is attracting attention as one of the new renewable energies that can replace fossil fuels. A clue came out to improve the performance of the Cu2O photoelectrode that produces hydrogen by decomposing water using infinite solar energy. Cho group’s research team developed a new photoelectrochemical oxidation process that controls the oxidation rate on the surface of the Cu2O thin film and synthesized a high-quality CuO Ultra-thin film. The photoelectrode of a heterojunction structure in which a CuO ultra-thin layer is stacked on Cu2O obtained a high photocurrent value of about 8.3 mA/cm2 under standard sunlight conditions. This is a description that is higher than all oxide hydrogen electrodes reported to date.
