Multi-wall carbon nanotube@zeolite imidazolate framework composite from a nanoscale zinc oxide precursor

•We synthesize nanocomposite of MWCN@ZIF.•We propose a heterogeneous crystallization mechanism from ZnO precursor.•The nanocomposite displays a capacity of 380 mAh/g in Li–sulfur battery.

Nanocomposite of multi-walled carbon nanotube@zeolite imidazolate frameworks (MWNT@ZIF) was prepared through a nanotube-facilitated growth based on a nanosized ZnO precursor. The electrically conductive nanocomposite displays a capacity of 380 mAh/g at 0.1 °C in Li–sulfur battery, transforming electrically inactive ZIF into the active one for battery applications.
