Herein, efficient ZnFe₂O₄ nanoparticle (NP)-decorated V₂O₅ nanostructure photocatalysts were synthesized for photoelectrochemical applications, and their crystalline structure, morphology, and optical properties of the synthesized samples were analyzed. The ZnFe₂O₄ NP decoration over the V₂O₅ nanostructure surface significantly influenced the optical properties with the optical bandgap varying from 2.12 to 2.20 eV. The charge-transfer kinetics were investigated through electrochemical impedance spectroscopy. The ZnFe₂O₄ NP-decorated V₂O₅ nanostructures exhibited the lowest charge-transfer resistance of 4.69 KΩ and maximum photocurrent density of ~0.17 × 10^-3 A cm^-2 in the light state, which is six times higher than that of pure V₂O₅ nanostructures. Further, Mott–Schottky (M–S) analysis was performed at fixed frequencies, which significantly influenced the flat potentials and carrier densities owing to the ZnFe₂O₄ NP decoration.
