PHOTOCATALYST BODY, PHOTOCATALYST DISPERSION, AND METHOD FOR PRODUCTION OF PHOTOCATALYST BODY

摘要

PROBLEM TO BE SOLVED: To provide: a photocatalyst body capable of preventing deterioration of the catalyst activity of a photocatalyst; a photocatalyst dispersion; and a method for production of the photocatalyst body.

SOLUTION: There is provided the photocatalyst body including at least one particulate selected from a tungsten oxide particulate and the particulate of a tungsten oxide composite material. There is also provided a method for production of the photocatalyst body, characterized by satisfying the respective specific values in absorption intensity ratio at specific wavelength and maximum peak intensity ratio when the photocatalyst body is analyzed through an infrared spectroscopy and a near-infrared spectroscopy.
