Visible-light induced superhydrophilicity on a WO(3)/ITO/CaFe(2)O(4) heterojunction thin film.
The WO(3)/ITO/CaFe(2)O(4) film surface showed visible-light induced superhydrophilicity, which is ascribed to efficient charge separation, resulting from the recombination of photo-electrons from WO(3) with photo-holes from CaFe(2)O(4) in the ITO layer.
