CeO2/ZnO nanotube array films grown on FTO substrates are successfully synthesized by a two-step electrodeposition process. The CeO2/ZnO nanotube array films exhibit substantially enhanced photocatalytic activity with a hydrogen evolution rate of 2.7 mu mol cm(-2) h(-1) under white light irradiation and excellent stability. Moreover, the collection and recycle of these immobilized CeO2/ZnO nanotube array films are much easier compared with the powder photocatalysts. (C) 2013 Elsevier B.V. All rights reserved.
