    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.
