NANO PHOTOCATALYST SOL AND ITS APPLICATION

摘要

PROBLEM TO BE SOLVED: To provide a sol of a nanosized photocatalyst and its application.

SOLUTION: The sol of a spherical nano photocatalyst and a nonspherical nano photocatalyst is used in order to coat a photocatalyst layer on a base material. A coating layer of the photocatalyst which is hard and has a good adhesion and a good photocatalyst activity, can be obtained without a binder because of a stereospecific and tangled composite structure between the spherical photocatalyst and the nonspherical photocatalyst.
