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 CoS2 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 CoS2 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 CoS2 nanobubble hollow prisms show remarkable electrochemical performance with good rate capability and long cycle life.
