Synthesis of Multiple‐Shell WO₃ Hollow Spheres by a Binary Carbonaceous Template Route and Their Applications in Visible‐Light Photocatalysis

Hollow go lightly: Well-defined multiple-shell WO3 hollow spheres were synthesized by a facile binary carbonaceous spheres template route. Compared with single-shell WO3 hollow spheres, the unusual porous multiple-shell structure of the WO3 hollow spheres proves to greatly enhance photocatalytic activity toward degradation of organic pollutants under visible-light irradiation.
