Abstract

The photocatalytic activity of a series of titanium dioxides in the oxidation of X-3B pigment is investigated. The factors including crystallite size, lattice distortion and anatase content that influence the photocatalytic activity of titanium dioxide dispersion are discussed in detail. We propose that lattice distortion that inhibits the hole and electron pair recombination dominates the above factors and to some extent determines the photocatalytic efficiency of titanium dioxide dispersions.

Key words: TITANIUM DIOXIDE, CRYSTAL STRUCTURE, PHOTOCATALYSIS, ABERRATION, CRYSTAL FIELD
