Self-organized Titania nanotubes grown on a titanium foil by anodization is loaded with Ag3PO4 using successive ionic layer adsorption and reaction method. The hybrid heterojunction nanostructure film thus prepared is investigated for visible light induced photocatalytic decomposition of azo-dye and compared with the bulk Ag3PO4 film deposited on a Ti-substrate. The results demonstrate that the hybrid heterostructure exhibits much better photocatalytic performance due to the higher photostability. (C) 2014 Elsevier B.V. All rights reserved.
