PHOTOCATALYST COMPOSITION HAVING VERY EXCELLENT PHOTOCATALYST FUNCTIONS EVEN UNDER NATURAL LIGHT AND LIGHT OF INDOOR LAMPS AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: To provide a photocatalyst composition capable of maintaining an effect of photocatalyst while preventing damage of photocatalsyt particles and photocatalyst functions, maintaining strong adhesive force on the surface coated with the composition and preventing loss of efficacy of the composition for a long time, and a manufacturing method of the photocatalyst composition. CONSTITUTION: The photocatalyst composition comprises a selenium sol, and titanium dioxide photocatalyst, wherein an Anatase titanium dioxide sol is coated on an upper part of the selenium sol that is a primer layer, and wherein solid content of the selenium sol is 3 wt.% of solid of the titanium dioxide photocatalyst. The manufacturing method of the photocatalyst composition comprises the steps of preparing a selenium sol; mixing the selenium sol with a titania sol; and heating the mixture at 100 deg.C for 10 to 60 minutes.
