1. A ternary composite material comprising:
a scaffold formed of carbon nanotubes (CNT);
a first layer of zeolitic imidazolate 8 (ZIF-8) crystals formed on the scaffold of the CNT; and
a second layer of molybdenum disulfide (MoS2) flakes formed on the first layer of the ZIF-8 crystals,
wherein the ZIF-8 crystals are thiolated, and
wherein sulfur vacancies of the MoS2 flakes are bound to thiol group binding sites of the ZIF-8 crystals.
