Herein, a multi-metallic Cu/Fe-Co/G nanocomposite was synthesized by decorating Cu on Fe-doped ZIF-67 (FZIF67) supported on graphene oxide (GO) through a pyrolysis strategy. The synthesized nanocomposites were characterized by their structural and morphological features using FT-IR, XRD, XPS, FE-SEM (coupled with elemental mapping), EDX, and BET analyses. The results revealed that Cu decoration on the FZIF67/rGO significantly affects the crystalline structure and surface area of the nanocomposite. Owing to the synergistic interaction between Cu, Fe, and Co with GO nanosheets, the Cu/Fe-Co/G composite exhibited superior electrocatalytic activity, achieving overpotentials of only 292 mV for OER and 308 mV (272 mV) for HER to reach a current density of 10 mA cm<sup>−2</sup> in 1.0 M KOH (0.5 M H<sub>2</sub>SO<sub>4</sub>) media. Moreover, the catalyst delivered a Faradaic efficiency of 97.9% and excellent durability over 25 h of continuous operation.
