Single-Step Electrodeposition of ZnO Nanoparticles Decorated (111)-Textured Cu₂O Films with Enhanced Photoelectrochemical Properties.

ABSTRACT: Cuprous oxide (Cu₂O) is a promising material for photoelectrochemical water splitting due to its favorable band structure, environmental acceptability, nontoxicity, and ease of fabrication. In this study, (111)-textured Cu₂O films decorated with numerous ZnO nanoparticles (NPs), namely ZCO films, are synthesized by a facile one-step electrodeposition method. The mechanism for forming ZnO NPs during the electrodeposition of Cu₂O films is proposed. Based on the Mott-Schottky analysis and electrochemical impedance spectroscopy measurements, the presence of ZnO NPs on the Cu₂O films enhances band bending and reduces charge transfer resistance to the electrolyte, which is advantageous for separating photoexcited electron and hole carriers in the illum
