Abstract

In this work, solvothermal methods were used to create CdS nanorods (NRs) on Cd foil. Furthermore, a second hydrothermal procedure was performed in water to improve the photoelectrochemical (PEC) properties of the base material at different time variations (3, 6, and 12 h at 160 °C). After the second hydrothermal process, self-assembled Cd(OH)₂ NWs were grown on CdS NR. The optimized Cd(OH)₂ NW/CdS NR-6 h photoanode exhibited a higher photocurrent density of 5.7 mA/cm⁻² at 0 V vs. Ag/AgCl under one sun illumination. Also, the optimum Cd(OH)₂ NW/CdS NR-6 h photoanode showed a hydrogen evolution rate of 216 μmol cm⁻² for 3 h. The enhanced PEC performance is mainly attributed to the removal of organic moieties, the partial transformation of self-assembled Cd(OH)₂ NWs to CdS NR during PCE measurement, and provided effective charge separation and delayed the recombination. We believe that the findings of this study will provide guidelines for designing and fabricating sunlight-driven photoanodes for the PEC hydrogen production system.
