Publication number: 20120270977Abstract: A titanium dioxide dispersion liquid in which the transmittance is 80% or more is manufactured by dispersing titanium dioxide fine particles having an average primary particle diameter of 1 nm or more and 30 nm or lower in a solution containing diglyme which is a solvent and trimethoxypropylsilane which is a dispersant. By doping titanium dioxide fine particles with nitrogen atoms, and then dispersing the same by an atomization device using beads having an average particle diameter of 15 ?m or more and 30 ?m or lower, a titanium dioxide dispersion liquid capable of maintaining transparency stability over a long period of time is manufactured.Type: ApplicationFiled: March 27, 2012Publication date: October 25, 2012Applicant: CANON KABUSHIKI KAISHAInventors: Katsumoto Hosokawa, Terunobu Saitoh, Kikuo Okuyama

Publication number: 20120270028Abstract: The invetion relates to a titanium dioxide-based photocatalyst containing carbon that is highly photoactive in visible light (vlp-TiO2) and to a method of manufacture. The vlp-TiO2is manufactured by mixing a fine grained titanium compount (BET?50 m2/g) with an organic carbon compound and subsequent thermal treatment at temperatures up to 350° C. The carbon content amounts to 0.05 to 4% by weight, preferably 0.4 to 0.8% by weight. The product is characterized by an ESR spectrum which displays only one significant signal in the g value range from 1.97 to 2.05 at g about 2.003. The inventive photocatalyst can be used for to degrade contaminants and pollutants in liquids and gases.Type: ApplicationFiled: April 21, 2009Publication date: October 25, 2012Applicant: Kronos International Inc.Inventors: Jurgen Orth-Gerber, Horst Kisch, Shanmugasundaram Sakthivel
