PROBLEM TO BE SOLVED: To obtain a photocatalyst which can utilize the good catalytic capacity of anatase-type titanium oxide without deteriorating a base material constituent when mixed into the constituent by coating the anatase-type titanium oxide with a porous substance. SOLUTION: In this photocatalyst which is used for the decomposition and removal of environmental pollutants in water and air, deodorization, sterilization, etc., anatase-type titanium oxide is coated with a porous substance, the direct contact between a photo-semiconducting substance and a base material constituent is prevented by the coating layer, and simultaneously a state in which the photo-semiconducting substance is not cut off from light is materialized. As a form to coat the titanium oxide with the porous substance, for example, a porous microcapsule containing titanium oxide etc., are named. Preferably, a conductive substance which is brought into contact with the anatase-type titanium oxide is made to exist, and a polyolefin, polyurethane, etc., are made to be a matrix component. |
