Abstract
This study focuses on the synthesis, characterization, and photoelectrochemical
evaluation of Fe2O3-TiO2 nanotubes (NTs) films for water-splitting applications to produce
hydrogen. TiO2 nanotubes were fabricated using an anodization method, while
Fe2O3nanoparticles were deposited onto the nanotubes via an impregnation technique. The
aim was to develop nanomaterials with controlled crystal size, morphology, and enhanced
electronic and optical properties to improve photoelectrochemical performance. Two
synthesis strategies were employed: (1) electrochemical anodization at 20 V for 1 hour to
produce TiO2NTs, and (2) impregnation with an iron-containing solution followed by thermal
treatment to form Fe2O3-TiO2 hybrid films. The materials were evaluated using a solar
simulator and potentiostat to assess their suitability for hydrogen generation through photoelectrolysis.
