摘要：

Titanium-vanadium oxide films have been prepared by the sol-gel method using a starting solution containing titanium isopropoxide and vanadium(IV) oxyacetyl acetonate. Solid solubility of VO2 in TiO2 matrix and the effects of vanadium incorporation on the crystallization behavior of TiO2 were investigated by an X-ray diffraction analysis. It was found that the absorption edge of Ti1-xVxO2 films shifted to longer wavelengths when x increased. The sol-gel derived Ti0.95V0.05O2 film electrode was found to exhibit a conspicuous photoresponse in the visible region. Moreover, this film electrode was proved to be photoelectrochemically quite stable. (C) 1999 Elsevier Science S.A. All rights reserved.
