Photoelectrochemical Hydrogen Generation in Coral-like TiO2 Photoanode

Abstract

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.
