Abstract

Graphene-coated l₂O₃ (GCA)-TiO₂ nanocomposite photoanodes were fabricated by dispersing the GCA (1, 3, and 5wt.%) and TiO₂ nanoparticles. Photoelectrochemical (PEC) responses under the white light illumination were significantly enhanced with the increase of the GCA content and all of the GCA-TiO₂ films exhibited much better PEC responses than the electrode prepared from the TiO₂ alone. The significantly improved PEC response of the GCA-TiO₂ can be attributed to the enhanced electron transport.
