Abstract
This document provides a testing method for testing phenol oxidative decomposition performance of semiconducting photocatalytic materials or made of a material adsorbed with photocatalyst to its surface for the purpose of purifying water polluting substances in water making use of photocatalytic performance as test piece. The test piece can be planar, spherical, flake or block shape. A test piece that can elute hydrocarbon or the like by immersion into water or phenol aqueous solution or by light irradiation, a semiconducting photocatalytic material that cannot maintain its shape or a powdery semiconducting photocatalytic material are excluded from the scope of application, since they cannot be evaluated.
