A scavenger-free and self-powered photoelectrochemical sensor is developed to rapidly detect hydrogen peroxide (H2O2) in the aqueous phase. The resulting CuO/ZnO photocathode composite exhibits two-times higher photocurrent density than the bare CuO under simulated sunlight irradiation, attributed t...
