The influence of dissolved cupric and ferric ions on the photocatalytic degradation of phenol in aqueous dispersions of titanium dioxide was investigated. At pH 3.5 both ion species enhanced the TiO2 photocatalytic activity until an optimum metal concentration was reached (1×10−3 M for Cu2+ and 7×10−6 M for Fe3+). Beyond these values the activity was observed to decrease, what was mainly attributed to precipitation of metal derivatives. A mechanism based in the formation of a complex between the metal and the organic compound adsorbed onto the titania surface is proposed to explain the observed positive effect of copper and iron ions addition.
