Summary:This study presents the chemical transformation of nickel-based metal-organic frameworks into binary metal-organic frameworks by introducing cobalt metal ions. The resulting NiCo-BDC hierarchical nanostructure exhibited higher oxidation states, resulting in an impressive capacitance of 1431 F g −1 . Additionally, the device based on this material exhibited exceptional capacity retention over 3000 cycles. The fabricated hierarchical nanostructure based on NiCo-metal-organic frameworks provides numerous pathways for electron transport, resulting in increased capacitance and superior rate performance.
