Photoelectrochemical Hydrogen Generation in Coral-like TiO2 Photoanode

The coral-like TiO2 nanoparticles were synthesized on the transparent FTO conductive substrate and their photovoltaic properties investigated under illumination. Coral-like TiO2 photoanodes were synthesized using a hydrothermal method and annealed at 450 °C to obtain better crystallinity. Annealed coral-like TiO2 show a photocurrent enhancement of ~50% compared to pristine coral-like TiO2 without annealing using 1M Na2SO4 as electrolyte at potential of 0 V.
