Notes:
To improve its visible light response capability, a new narrow bandgap zinc ferritesemiconductor was in-situ introduced into the matrix of titanium dioxide nano film. ZnFe2O4 doped TiO2composite films have been successfully formed on glass and stainless steel substrates from aqueoussolution through equilibrium reaction between iron (III)-titanium (IV)-fluoric complex and boric acid,followed by in-situ hydrothermal conversion and crystallization in the Zn2+-contained basic environment.The obtained films were densely packed and had no visible cracks; clear photovoltaic responses wereobserved in the anodic direction, and they were much larger in the presence of ferrite dopant. It issuggested that the shift of the corrosion potential was ascribed to photo-induced charge separationbetween the conduction band of ZnFe2O4 and its counterpart TiO2 nano-particles
