Abstract: Nanosized porous TiO2 films supported on nickel are prepared by solgel process. The STM morphology of the nanosized TiO2 films has been given. It is known by STM, that the diameter of TiO2 particles is about 20~80 nm and the pore quantity and the diameter of nanosized TiO2 film increase with the increasing of sintering temperature. The photoelectrochemical performance of the prepared TiO2 photoelectrode is determined by cyclic voltammitric method. It is found that the photocurrent of the photoelectrode increases with the increasing of the sintering temperature and thickness of TiO2 film.

Key words: Sol-gel, TiO2, Nanosized film, Cyclic voltammitric method,  Photoelectrochemical property
