摘要

Nanorods of cadmium selenide (CdSe) have been successfully synthesized through cadmium hydroxide nanowires as template deposited by chemical bath deposition (CBD) followed by anion exchange route to exchange hydroxyl ions by selenium based on the negative free energy of formation with aid of solubility product for various conversion time to get optimum. Synthesized CdSe nanorods exhibited well-defined structural and morphological characteristics, confirming successful conversion; enabling efficient light-harvesting capabilities toward superior photoelectrochemical (PEC) performance which is well supported through increased photocurrent density, favorable charge carrier behavior from the Mott-Schottky analysis, and reduced charge transfer resistance observed in electrochemical impedance spectroscopy (EIS) measurements. Optimum CdSe nanorods achieved nearly fourfold (0.118%) efficiency compared to the CdSe flat layer (0.031%), showing significant potential of improved efficiency through nanostructured surface architecture.
