PHOTOCATALYST COMPOSITE MATERIAL, APPLICATION LIQUID FOR FORMING PHOTOCATALYST LAYER, AND STRUCTURE CARRYING PHOTOCATALYST

摘要

A photocatalyst composite material containing a photocatalyst and colloidal silica particles, characterized in that the colloidal silica particles comprises spherical colloidal silica particles bonded to one another so as to form a long and narrow shape and the photocatalyst composite material further comprises at least one compound selected from the group consisting of a zirconium compound and an aluminum compound. The photocatalyst composite material can be used for providing a structure carrying a photocatalyst which is useful for water clarification, deodorization, anti−staining, sterilization, waste water treatment, suppression of growth of an alga, and various chemical reactions.
