Hollow Spheres: MS2 (M = Co and Ni) Hollow Spheres with Tunable Interiors for High‐Performance Supercapacitors and Photovoltaics (Adv. Funct. Mater. 15/2014)

S. Peng, S. Ramakrishna, Q. Yan, and co-workers demonstrate a solutionbased route for the synthesis of CoS2 and NiS2 hollow spheres with various interiors. The obtained CoS2 hollow spheres display superior performances in supercapacitors and dye-sensitized solar cells. This work provides a promising approach for the design and synthesis of structurally tunable materials with greatly enhanced supercapacitor behavior, which could be applied in energy conversion and storage devices.
