Abstract: A photo-catalyst and a method for manufacturing the same are provided to improve the visible-light activity on pollutants of the photo-catalyst, thereby removing the pollutants under visible light, by manufacturing the photo-catalyst where Pt is supported on a photo-catalyst of ZnS-ZnO having a sensitivity on the visible light. A mixture solution is prepared by inputting a chloroplatinic acid solution into a composite photo-catalyst of ZnS-ZnO, and is purged for 30 minutes or more(S110). A photo-catalyst solution of Pt/ZnS-ZnO is prepared by applying light to the mixture solution(S120). The photo-catalyst solution of Pt/ZnS-ZnO is filtered(S130). The filtered photo-catalyst solution of Pt/ZnS-ZnO is dried(S140). In the photo-catalyst of Pt/ZnS-ZnO, Pt is photo-supported on the composite photo-catalyst of ZnS-ZnO.
