Abstract: This paper describes a study for the behavior of light induced charges on the surface of ul-trafine particle TiO2(UFP-TiO2) by surface photovoltage spectroscopy(SPS). It is found that the SPSresponse of TUP-TiO2is very sensitive to some gases adsorbed. The interaction and the processes of charge transfer between the surface and adsorbate have been discussed.

Key words: Ultrafine particle, Charge transfer on interface, Surface photovoltage
