DECOMPOSITION CATALYST FOR HYDROGEN PEROXIDE FOR DISINFECTING CONTACT LENSES, AND METHOD FOR MANUFACTURING DECOMPOSITION CATALYST

Document Type and Number:

WIPO Patent Application WO/2020/202320

Kind Code:

A1

Abstract:

The present invention provides a decomposition catalyst for hydrogen peroxide for disinfecting contact lenses, the decomposition catalyst having excellent durability. This catalyst is a decomposition catalyst for hydrogen peroxide for disinfecting contact lenses, the decomposition catalyst containing a carrier and platinum-containing microparticles fixed onto the carrier, wherein: the carrier has a substrate and a coating layer provided on the surface of the base; and the coating layer includes a polymer that includes repeating units having an aromatic ring substituted by two or more hydroxyl groups, and a heteroatom having a lone electron pair.
