Preparation of nanoporous BiVO₄/TiO₂/Ti film through electrodeposition for photoelectrochemical water splitting.

ABSTRACT: A nanoporous BiVO₄/TiO₂/Ti film was successfully fabricated by electrodepositing a nanoporous BiOI film on nanoporous TiO₂ arrays followed by annealing at 450°C for 2 h. The electrodeposition of BiOI film was carried out at different times (10, 30, 100, 500 and 1000 s) in Bi(NO₃)₃ and KI solution. The morphological, crystallographic and photoelectrochemical properties of the prepared BiVO₄/TiO₂/Ti heterojunction film were examined by using different characterization techniques. UV-vis spectrum absorption studies confirmed an increase in absorption intensities with increasing electrodeposition time, and the band gap of BiVO₄/TiO₂/Ti film is lower than that of TiO₂/Ti. The photocatal
