Abstract

TiO2powders were coated with polypyrrole layers by irradiating dispersions of them in a solution containing pyrrole, oxygen, and fluoroborate ion with UV light. Polymer-coated and platinized powders were photoactive despite some losses, probably due to absorption by the polymer layer. Incorporating the anionic chromophore fluorescein into the positively charged polypyrrole structure sensitized the photocatalytic generation of hydrogen with visible light.
