PHOTOELECTROCHEMICAL STUDIES OF COLLOIDAL TIO2 FILMS - THE EFFECT OF OXYGEN STUDIED BY PHOTOCURRENT TRANSIENTS

• The effect of oxygen in nanocrystalline colloidal TiO2 film photoelectrodes have been investigated by means of optically induced photocurrent transient measurements. It was concluded that O-2 played an important role in the recombination of electrons and
