  "abstract": "The heterojunction of the Cu2O/TiO2 nanorod photoelectrode was synthesized via a facile hydrothermal method and electrodeposition method. The influence of Cu2O deposition on the structural, optical, and photoelectrochemical properties of the photoelectrodes was systematically investigated through comprehensive physicochemical characterization. Under AM 1.5 simulated solar illumination, the optimized Cu2O/TiO2 nanorod photoelectrodes achieved a photocurrent density of 1.30 mA cm−2 at 1.23 V vs. RHE in an ethanol-containing electrolyte. The enhanced photoelectrochemical performance was attributed to improved light utilization and more efficient charge separation with suppressed electron-hole recombination resulting from the formation of the Cu2O/TiO2 heterojunction. Simultaneously, ethanol also served as a sacrificial electron donor in the proposed system. Notably, the Cu2O/TiO2 nanorod photoelectrodes can be promising photoelectrodes for solar-driven hydrogen production with a simple, economical, and environmentally friendly approach.",
