Hollow go lightly : Well‐defined multiple‐shell WO 3 hollow spheres were synthesized by a facile binary carbonaceous spheres template route. Compared with single‐shell WO 3 hollow spheres, the unusual porous multiple‐shell structure of the WO 3 hollow spheres proves to greatly enhance photocatalytic activity toward degradation of organic pollutants under visible‐light irradiation.
