Influence of Cu distribution on photocatalytic activity of Cu-doped titania prepared using metal alkoxides

Influence of Cu distribution on photocatalytic activity of Cu-doped titania prepared using metal... Cu-doped titania was prepared from sols containing titanium tetraisopropoxide (TTIP) and copper(II) isopropoxide (CIP). The Cu distribution in the titania was controlled by varying the reaction time of the TTIP at which the CIP was added to the sol. The photocatalytic activities of the samples were evaluated by the hydroxyl radical production during UV and visible irradiations. The influences of the Cu distribution in the titania and the electronic interaction between the Ti and Cu on the photocatalytic activity were discussed. The sample prepared by adding CIP after some reaction time of TTIP exhibited a higher activity than that prepared by initially mixing TTIP and CIP. The impurity states of Cu2+ on the titania surface effectively trapped the electrons in the conduction band of the titania and received the electrons in the valence band upon photoexcitation, and consequently, suppressed charge recombination of the electrons and holes. In the sample, the high Cu distribution on only the titania surface rather than inside the titania bulk led to its high photocatalytic activity. Research on Chemical Intermediates Springer Journals
