Abstract
Hierarchical tubular structures composed of Co<sub>3</sub>O<sub>4</sub> hollow nanoparticles and carbon nanotubes (CNTs) have been synthesized by an efficient multi-step route. Starting from polymer-cobalt acetate (Co(Ac)<sub>2</sub>) composite nanofibers, uniform polymer-Co(Ac)<sub>2</sub>@zeolitic imidazolate framework-67 (ZIF-67) core-shell nanofibers are first synthesized via partial phase transformation with 2-methylimidazole in ethanol. After the selective dissolution of polymer-Co(Ac)<sub>2</sub> cores, the resulting ZIF-67 tubular structures can be converted into hierarchical CNTs/Co-carbon hybrids by annealing in Ar/H<sub>2</sub> atmosphere. Finally, the hierarchical CNT/Co<sub>3</sub>O<sub>4</sub> microtubes are obtained by a subsequent thermal treatment in air. Impressively, the as-prepared nanocomposite delivers a high reversible capacity of 1281 mAh g<sup>-1</sup> at 0.1 A g<sup>-1</sup> with exceptional rate capability and long cycle life over 200 cycles as an anode material for lithium-ion batteries. © 2016 Wiley-VCH Verlag GmbH & Co.
