摘要： Provided is a method of producing a catalyst or adsorbent carrier and a catalyst or adsorbent carrier which can enhance a catalyst or adsorbent function, and prevent fall-off of catalyst particles or adsorbent particles. The surface of a metal base material made of aluminum or an aluminum alloy is subjected to an etching process using an etchant containing iron chloride and an oxide to convert the surface to an uneven and rough surface. The uneven and rough surface of the metal base material is subjected to an anodizing process to form a porous coating along the uneven and rough surface. A large number of catalyst or adsorbent particles are thus carried on the surface of the metal base material on which the porous coating is formed along the uneven and rough surface.

摘要： Provided is a photocatalytic device capable of further enhancing an effect by a photocatalyst and also efficiently dissipating heat emitted from a light applying portion, and capable of further enhancing the purification effect by increase of a light amount. In the photocatalytic device, both end portions of a housing in the lateral direction are in contact with an upper face of a photocatalyst filter to support the photocatalyst filter, and form upper-side edge portions for openings. A center portion of the housing is distant from the photocatalyst filter in an upward direction. Tilted portions are positioned in regions between both the end portions and the center portion. A lower-side inner wall of the housing supports the photocatalyst filter, and forms lower-side edge portions for the openings. A light applying portion is disposed on a lower face of the center portion of the upper-side inner wall.
