摘要 A TiO2 modified with PtⅣ chloride was investigated by diffuse reflectance UV-Vis spectra(DRS),X-ray photoelectron spectroscopy(XPS), surface photovoltage spectroscopy(SPS) and electric field-induced surface photovoltage spectroscopy(EFISPS).XPS showed that a Ti-O-PtⅣClx surface complex between PtⅣ chloride and TiO2 appears to be responsible for visible light absorption.An electron transfer from the surface-complexed PtⅣClx to the conduction band of TiO2 upon absorbing visible light was confirmed by SPS and EFISPS. A TiO2 modified with Pt^Ⅳ chloride was investigated by diffuse reflectance UV-Vis spectra ( DRS), X-ray photoelectron spectroscopy (XPS), surface photovohage spectroscopy(SPS) and electric field-indueod surface photovoltage spectroscopy(EFISPS). XPS showed that a Ti-O-Pt^Ⅳ Clx surface complex between Pt^Ⅳ chloride and TiO2 appears to be responsible for visible light absorption. An electron transfer from the surfaceeomplexod Pt^Ⅳ Clx to the conduction band of TiO2 upon absorbing visible light was confirmed by SPS and EFISPS.
