Abstract
A simple and versatile method for general synthesis of uniform one-dimensional (1D) M<sub>x</sub>Co<sub>3-x</sub>S<sub>4</sub> (M=Ni, Mn, Zn) hollow tubular structures (HTSs), using soft polymeric nanofibers as a template, is described. Fibrous core-shell polymer@M-Co acetate hydroxide precursors with a controllable molar ratio of M/Co are first prepared, followed by a sulfidation process to obtain core-shell polymer@M<sub>x</sub>Co<sub>3-x</sub>S<sub>4</sub> composite nanofibers. The as-made M<sub>x</sub>Co<sub>3-x</sub>S<sub>4</sub> HTSs have a high surface area and exhibit exceptional electrochemical performance as electrode materials for hybrid supercapacitors. For example, the MnCo<sub>2</sub>S<sub>4</sub> HTS electrode can deliver specific capacitance of 1094 Fg<sup>-1</sup> at 10 Ag<sup>-1</sup>, and the cycling stability is remarkable, with only about 6% loss over 20000 cycles. © 2015 WILEY-VCH Verlag GmbH & Co.
