摘要
Abstract Metal–organic frameworks (MOFs) have been intensively used as the templates/precursors to synthesize complex hollow structures for various energy‐related applications. Herein we report a facile two‐step diffusion‐controlled strategy to generate novel MOFs derived hierarchical hollow prisms composed of Nanosized CoS 2 bubble‐like subunits. Uniform zeolitic imidazolate framework‐67 (ZIF‐67) hollow prisms assembled by interconnected nanopolyhedra are first synthesized via a transformation process. Afterwards, these ZIF‐67 building blocks are converted into CoS 2 bubble‐like hollow particles to form the complex hollow prisms through a sulfidation reaction with an additional annealing treatment. When evaluated as an electrode material for lithium‐ion batteries, the as‐obtained CoS 2 nanobubble hollow prisms show remarkable electrochemical performance with good rate capability and long cycle life.
