TiO2 thin films prepared by EISA method show appreciable photoelectrochemical response towards oxygen evolution.Highly crystalline mesoporous thin films show better performance than dense (non-porous) or non-crystalline films. The addition of CoPi cocatalyst presents two regimes:At low potentials, CoPi deposition decreases the photocurrent.At high potentials, CoPi intrinsic electrocatalytic activity improves the performance.
