VISIBLE LIGHT RESPONSIVE PHOTOCATALYST MATERIAL, VISIBLE LIGHT RESPONSIVE PHOTOCATALYST COATING MATERIAL, VISIBLE LIGHT RESPONSIVE PHOTOCATALYST BODY AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a visible light responsive photocatalyst material, visible light responsive photocatalyst coating material, visible light responsive photocatalyst body and lighting device, in which a performance of decomposition activity of a photocatalyst can be exerted to a range separated from a surface of the photocatalyst and the performance of the decomposition activity is easily stabilized.

SOLUTION: There is provided the visible light responsive photocatalyst material of tungsten trioxide fine particles or consisting essentially of tungsten trioxide fine particles in which activation molecules having an oxidization action are released in an atmosphere by irradiation with visible light.
