Document Type and Number:
Japanese Patent JP4174087
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photocatalyst having a high photocatalytic activity and an abundance of adaptability and a water purification device using the photocatalyst. SOLUTION: A photocatalyst composite body 1 has a photocatalyst film 5 and an electrically-conductive film 3 provided in an adjacent relation with the photocatalyst and having transmissibility against light having wavelengths capable of activating the photocatalyst and is supported by a light-transmissive support 7. Thickness of the photocatalyst 5 is within a range of 50-500 nm. In this constitution, activity of the photocatalyst can be maintained at a high level for a long time and effective purification of water can be carried out.
