When the photocatalytic properties of m - Pt - WO3 nanohybrids were systematically investigated , it was revealed that the m - Pt - WO3 nanohybrids showed great promise for degrading the organic dye under visible light irradiation , which shows an excellent photocatalytic activity that far exceeded those of pure phase mesoporous WO3 and commercial TiO2 ( P25 ) , and was 10 - fold more active than that of the bulk Pt - WO3 catalyst .
