Enhanced photocurrent and photocatalytic degradation of methyl orange in cobalt hydroxide loaded titanium dioxide film
We report experimental investigation of the effect of the cobalt hydroxide (Co(OH)2) decoration on the photocatalytic activity of the titanium dioxide (TiO2) films. We demonstrate that the decoration of Co(OH)2 is able to red-shift the absorption edge of the TiO2 film from UV to the visible light re...
