【Abstract】 In the paper.It is reported that several viologens and the surfactant N-CPC (Ncetyl pyridinium chloride) conld promote the photochemical cleavage of water on pt/ TiO2 powder-H2o sostem under illumination of UV light.The charaderistic colour(blue or violet) of the reduced viologens appeared when the TiO2-viologen system was illuminated.And the colour disappeared with H2-evolution when pt-cat was added to the above mentioned coloured suspensionThe amount of th evolved from pt/TiO2-system in the presence of N-CPC could be about 45 times higher than in the absence of it.The viologen was noted to be able to accept the excited electrons from TiO2 semiconducter.Those rusults have been discussed brifly.更多还原
