| Abstract: | This paper reports the synthesis and characterization of tungsten oxide by anodization method for 1 h using (1 M H2SO4, 1 M Na2SO4) electrolyte solution while varying NH4F concentration. The influence of NH4F concentration on structural, morphological, optical, and photocatalytic properties is examined. Scanning electron microscopy images show the formation of a thin layer with porous nanostructure attributed to the dissolution of anodic oxide by H+ and F− ions in the electrolyte under UV radiation of 365 nm. X-ray diffraction analysis reveals a mixed-phase crystal system of WO3, consisting of both monoclinic and tetragonal phases The crystallite size is found in the range 5.5‒18.2 nm with increasing NH4F concentration. UV–Vis spectroscopy analysis indicates a narrowing in the energy bandgap from 3.06 to 2.35 eV. Cyclic voltammetry manifests a decrease in the anodic peak current density with the rise in the concentration rate of NH4F. These findings extend a better understanding of the influence of NH4F concentration on the structural and electrochemical characteristics of the anodized nanoporous WO3 film as a potential candidate for hydrogen generation by the water-splitting process.
