DISPERSION LIQUID OF PHOTOCATALYST PARTICLE AND METHOD FOR PREPARING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a dispersion liquid in which photocatalyst particles are dispersed highly and to provide a method for preparing the dispersion liquid without using a dispersant. SOLUTION: The dispersion liquid contains a dispersion medium, the photocatalyst particles and an acidic substance, wherein the photocatalyst particles having≤50 nm average particle size (D50) when measured by a dynamic light scattering method are dispersed in the dispersion medium and the pH of the dispersion liquid is 1.0-6.5.
