Abstract In this work, solvothermally grown ZIF‐67 MOF crystals were utilized as single source molecular precursor, which were transformed into porous Co 3 O 4 nanoparticles through a simple calcination treatment. The crystal structure of ZIF‐67 was also authenticated by single crystal x‐ray analysis. Further, Co 3 O 4 nanoparticles were incorporated as supercapacitor electrode. The results show that ZIF‐67 derived Co 3 O 4 nanoparticles deliver an appreciable specific capacitance (190 F g −1 at 5 A g −1 ) with high capacitance retention (71.42% after 5000 cycles). The comparison with previous state‐of‐the‐arts highlights the importance of MOF derived nanomaterials for achieving superior electrochemical performance.
