Basing on normal pulse laser ablation (PLD) method, femtosecond pulsed laser deposition (fs-PLD) in vacuum has been adopted for the production of TiO2 nanoparticles(NPs) films on titanium. Annealed at 500? for 30minutes, the pure rutile and mixed phase can be obtained due to different deposition condition, different oxygen background gas pressure, from high vacuum (~10-6mbar) to 1 mbar, and different deposition time.Under one sun irradiation with a solar simulator (AM1.5),the photocurrent density of TiO2 NPs film with pure rutile phase is higher than that of TiO2 NPs film with mixed phase. The photoelectrochemical and charge transfer properties of the prepared photoanode were analyzed and disscussed in detailed.
