A Au/Cu 2 O–TiO 2 system for photo-catalytic hydrogen production. A pn-junction effect or a simple case of in situ reduction?

The Ni2+doped TiO2film (Ni-TiO2) was produced in-situ on the pure Ti plate substrate in the electrolyte solution of Na3PO4containing of Ni (Ac)2by micro-arc oxidation process (MAO). The effect of Ni (Ac)2content on structure and H2production activity of Ni-TiO2had been investigated. It was found that the characteristic peak (101) of anatase phase for Ni-TiO2decreased gradually without the peak of Ni and the red shift of its absorption edge appeared with the increase of Ni (Ac)2content. It was showed from experimental results that the highest H2production rate was 0.31 μmol/ h·cm2over the above-prepared Ni-TiO2at Ni (Ac)2content of 5 g/L.

Abstract: The Co2+ doped TiO2 film(Co-TiO2) was prepared by in-situ growing on the pure Ti plate substrate in the electrolyte solution of Na3PO4 containing CoSO4·7H2O by micro-arc oxidation (MAO) process. The effect of the amount of CoSO4·7H2O adding into the electrolyte solution on structure of Co-TiO2 and its activity of photo-catalytic hydrogen production had been studied. It was found that the characteristic peak(101) of anatase phase and the characteristic peak(002) of rutile phase appeared and the red shift of absorption edge occurred for Co-TiO2 films when adding CoSO4 into the electrolyte solution. It was shown from experimental results that the highest hydrogen production rate was 0.33 μmol/ h·cm2 over the above-prepared Co-TiO2 in CoSO4·7H2O content of 8.7 g/L.
