Title:
PHOTOCATALYST COATED BODY AND PHOTOCATALYST COATING LIQUID
Document Type and Number:
WIPO Patent Application WO/2012/014877
Kind Code:
A1
Abstract:
Disclosed is a photocatalyst coated body which has excellent photocatalytic degradation function and excellent weather resistance. Also disclosed is a photocatalyst coated body which is capable of suppressing the formation of intermediate products such as NO2, while increasing the amount of NOx removed during removal of NOx in the air. The photocatalyst coated body comprises a base and a photocatalyst layer that is provided on the base. The photocatalyst coated body is characterized in that photocatalyst layer contains 1-20 (inclusive) parts by mass of photocatalyst particles, 30-98 (inclusive) parts by mass of silica particles and 1-50 (inclusive) parts by mass of zirconia particles, so that the total of the photocatalyst particles, the silica particles and the zirconia particles is 100 parts by mass. The photocatalyst coated body is also characterized in that the zirconia particles are at least one kind of particles selected from the group consisting of crystalline zirconia particles having an average crystallite diameter of 10 nm or less and amorphous zirconia particles.
