PHOTOCATALYST PARTICULATE

摘要

PROBLEM TO BE SOLVED: To provide a photocatalyst particulate with easy recovery and recycling capable of exhibiting photocatalyst function without impairing function of the photocatalyst particle positioned not only at a surface side but also at an inner side even when it is made to a treatment structure such that it is filled in an optical-transparent vessel and treatment water is passed through the vessel. SOLUTION: The photocatalyst particulate is characterized in that the photocatalyst particulate such as apatite-coated titanium oxide is stored in a hollow shell formed by a thermoplastic resin such as polystyrene having optical transparency, gas-permeability and water-permeability obtained by a drying method in liquid and a particle diameter is 1 mm or larger.
