Correlation between Photocatalytic Activities and Structural and Physical Properties of Titanium(IV) Oxide Powders

Correlation between structural and physical properties and photocatalytic activities for five kinds of reactions of 35 titania samples was obtained through multivariable analyses: photocatalytic activities were empirically reproduced by a linear combination of six properties with fair reliability. While a portion of results could be interpreted using a conventional mechanism, significant activity dependence on properties, not disclosed yet, was suggested.
