Abstract
An object of the present invention is to provide a photocatalytic powder containing titanium dioxide fine particles containing an anionically active substance, where the electrokinetic potential of the fine particle is from about −100 to 0 mV in an aqueous environment at pH 5. Another object of the present invention is to provide a photocatalytic slurry containing the powder, and a polymer composition, a coating agent, a photocatalytic functional molded article and a photocatalytic functional structure using the powder.
Claims19
A photocatalytic powder comprising titanium dioxide fine particles comprising an anionically active substance, wherein the fine particles have an electrokinetic potential of from about −100 mV to −10 mV in an aqueous environment at pH 5, and wherein the titanium dioxide fine particles are obtained by a vapor phase reaction or a wet-hydrolyzing.
A photocatalytic powder comprising titanium dioxide fine particles comprising an anionically active substance, wherein the fine particles have an electrokinetic potential of from about −100 mV to −10 mV in an aqueous environment at pH 5, and wherein the crystal form of the titanium dioxide fine particles is anatase and/or brookite.
