Abstract

Water purification particles have porous particles and photocatalyst particles formed of titanium-based compound particles that are supported on the porous particles, have absorption at a wavelength of 500 nm in a visible absorption spectrum, and have an absorption peak at 2,700 cmto 3,000 cmin an infrared absorption spectrum, and a metal compound having a metal atom and a hydrocarbon group is bonded to the surface of each of the titanium-based compound particles through an oxygen atom.
