A method for producing photocatalyst particles capable of sufficiently exhibiting photocatalytic activity with a practical weak light source such as a fluorescent lamp, particles and powder, an organic polymer composition using the same, and the like Provided are a neutral and highly transparent slurry containing particles, a coating agent, a film having photocatalytic properties obtained therefrom, and an article having the same. A step of preparing an aqueous slurry containing titanium dioxide having a pH of 3 to 5, a step of preparing an aqueous solution containing an inactive compound as a photocatalyst, and reacting both in a pH range of 4 to 10. A process for producing composite particles of titanium dioxide and a compound that is inactive as a photocatalyst. [Selection figure] None |
