Effect of Heat Treatment on the Photocatalytic Activity of TiO₂ Thin Films Fabricated on Ti-6Al-4V Alloy

Abstract:

The self-organized oxide nanotube/pore layers were prepared by anodization on ternary Ti-6Al-4V alloys. The morphologies and structures of layers under different heat treatment tempreture were characterized by means of SEM, XRD, XPS and Raman spectroscopy and DRS. The effects of alloying element under different heat treatment tempreture on the structure, composition and opsorption property of the film catalysts were investigated along with their inherent relationships. The results show that two kinds of Ti-Al-V-O nanostructure grown inthe α and β phase region formed on the surface of the alloy. V doped-TiO₂ can inhibit the formation of anatase. The films show the microcrystalline structure of anatase and rutile and a small amount of V₂O₅ on the surface of film annealed at 400 oC. Moreover, the large surface and the synergy effect of V-doped TiO₂ and V₂O₅ make sample show the highest photocatalytic activity for the photocatalytic hydrogen evolution.
