Summary:Iron-tungsten/TiO 2 nanotube photoelectrodes have been synthesised by the anodisation process followed by the chemical bath deposition technique in this work. X-ray diffraction analysis, field emission scanning electron microscopy, UV-Vis, energy-dispersive X-ray spectroscopy and photoelectrochemical (PEC) measurements have been used to characterise these photoelectrodes. The ratio of the iron-tungsten deposited on TiO 2 nanotubes remarkably influences the PEC performance and the amount of hydrogen. The A1 photoelectrode showed the best PEC activity. The investigation of the recyclability of these new TiO 2 nanotubes indicated good stability of their photocatalytic activity. A simple method for the synthesis of high-performance PEC photoelectrodes with good stability and reliability has been provided by this work.
