N2 - Photoelectrochemical (PEC) water splitting offers a sustainable pathway for hydrogen production; however, its practical implementation is often limited by the poor efficiency and stability of photoelectrodes. In this work, porous cerium nickel oxide (CeNiO3) was synthesized via a simple citrate sol–gel method coupled with a hydrothermal approach and employed as a photoanode for PEC water splitting. The structural, morphological, and optical characteristics of the material were comprehensively investigated using XRD, UV-vis spectroscopy, FESEM, EDX, XPS, PL, and FTIR analyses. The optimized CeNiO3 photoelectrode demonstrated an excellent photocurrent density of 15.14 mA cm−2 at 1.4 V vs. RHE. Electrochemical impedance spectroscopy (EIS) revealed enhanced charge transfer kinetics and suppressed recombination of photoexcited charge carriers. The superior PEC activity of CeNiO3 is attributed to its bimetallic interactions, strong solar light absorption, efficient charge separation, and rapid charge transport. These results highlight the potential of CeNiO3 as a stable and efficient photoelectrode for solar-driven hydrogen generation.
