OA: closed
Abstract
The layers of Ti-Fe 2 O 3 /In 2 O 3 were prepared on the TiO 2 nanotubes using hydrothermal method. The obtained materials were tested as photoanodes for water oxidation under sunlight irradiation. Deposited films were characterized using scanning electron microscopy, X-ray diffraction, Raman spectroscopy, UV-Vis spectroscopy and X-ray photoelectron spectroscopy. The formation of heterojunction increases photocurrent of water oxidation at 1.0 V vs RHE to over 725 mA/cm 2 , while TiO 2 /In 2 O 3 and TiO 2 /Ti-Fe 2 O 3 exhibit only 254 and 306 mA/cm 2 , respectively.
