Abstract
Graphene-coated Al2O3 (GCA)-TiO2 nanocomposite photoanodes were fabricated by dispersing the GCA (1, 3, and 5 wt.%) 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.
