Abstract—Undoped and Ce(4+) doped TiO₂ thin films were prepared by solgel method. The samples were
characterized using scanning electron microscopy, the photocatalytic reactivity was evaluated by degradation
of methylene blue in the aqueous solution. 0.5 wt. % Ce(4+) doped TiO₂ thin films calcined at 400C show the
highest photocatalytic activity.
