Precisely tailoring ZIF-67 nanostructures from cobalt carbonate hydroxide nanowire arrays: toward high-performance battery-type electrodes

A facile transformation of a cobalt carbonate hydroxide nanowire array to a ZIF-67-based nanotube array was achieved, and the ZIF-67-derived mesoporous Co₃O₄ nanotube array exhibited remarkable electrochemical performance as a battery-type electrode due to its unique structure.
