摘要:
A photocatalyst coated body includes a base and a photocatalyst layer 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 all of these 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. Such photocatalyst coated body has excellent photocatalytic degradation function and excellent weather resistance; and also it 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.
