本文件提供了一种测试半导体光催化材料或被光催化剂吸附到其表面的材料的苯酚氧化分解性能的测试方法，目的是利用光催化性能作为试件净化水中的水污染物质。试件可以是平面、球形、片状或块状。可通过浸入水或苯酚水溶液或光照来洗脱碳氢化合物等的试样、无法保持其形状的半导体光催化材料或粉末状半导体光催化材料不在应用范围内，因为它们无法进行评估。

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.
