In Situ Preparation of Ni2+ Doped TiO2 Film on the Surface of Ti Plate and its Photo-Catalytic Hydrogen Production

Article Preview

Abstract:

The Ni2+ doped TiO2 film (Ni-TiO2) was produced in-situ on the pure Ti plate substrate in the electrolyte solution of Na3PO4 containing of Ni (Ac)2 by micro-arc oxidation process (MAO). The effect of Ni (Ac)2 content on structure and H2 production activity of Ni-TiO2 had been investigated. It was found that the characteristic peak (101) of anatase phase for Ni-TiO2 decreased gradually without the peak of Ni and the red shift of its absorption edge appeared with the increase of Ni (Ac)2 content. It was showed from experimental results that the highest H2 production rate was 0.31 μmol/ h·cm2 over the above-prepared Ni-TiO2 at Ni (Ac)2 content of 5 g/L.
