Cobalt-doped MnO2 with a hierarchical yolk–shell spherical structure has been prepared by a light-assisted method. The hierarchical spheres obtained are characterized by X-ray diffraction, nitrogen adsorption–desorption, and electron microscopy analyses. The supercapacitive performance of the materi...
