HIGH ACTIVE PHOTOCATALYST PARTICLE, METHOD FOR PRODUCTION THEREOF AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/053576
Kind Code:
A1
Abstract:
A method for producing a composite particle comprising titanium dioxide and a, which comprises a step of providing an aqueous slurry containing titanium dioxide and having a pH of 3 to 5, a step of providing an aqueous solution containing the compound having no photocatalytic activity and a step of reacting the both fluids at a pH ranging 4 to 10; a high active photocatalyst particle produced by the method; and the use of the photocatalyst particle.
