摘要：
UltrathinCo9S8nanosheets were successfully assembled into a carbon supported nanostructure of C@Co9S8core-shell hollow spheres by a facile solution-based method consisting of template-engaged growth of a precursor shell, followed by simultaneous sulfidation and removal of template. The prepared C@Co9S8hollow spheres exhibit enhanced electrochemical performance in supercapacitors due to their high surface area and excellent structural stability. (C) 2016 Elsevier B.V.
