Abstract

Unexpected photocatalytic properties of templated precursors of nanostructured TiO2(titania) were observed in the development of a generally applicable method for the synthesis of a truly nanocrystalline titania at temperatures compatible with plastic catalytic supports. It specifically comprised the “self-activation” feature of the TiO2nanostructured precursor (produced within the non-ionic surfactant template) likely induced by the preparation method “imprinted” photoactivity. Such behavior complied with the principal aim to develop the photocatalytic material without recourse to any significant thermal step.
