ABSTRACT The development of affordable and sustainable nanomaterials for energy storage is a top priority major focus within the global research community. Among these, carbon nano‐onions (CNOs) have emerged as promising material supercapacitors due to their distinctive morphology, high surface reactivity, microporous structure. Zeolitic imidazole frameworks (ZIFs), known vast area electrically active inorganic centers, potential storage. In this context, ZIF rhombic dodecahedron homogenously decorated with CNOs (size < 100 nm) form nanocomposite CNOs/ZIF (67 8) utilizing simple solvothermal technique. samples been characterized by Fourier transform infrared spectroscopy X‐ray diffraction techniques, which confirm successful synthesis samples. produced displays distinct dodecahedral shape, significant porosity, large specific (SSA) confirmed N 2 sorption studies. as‐prepared are further tested electrode supercapacitors, among them, CNO/ZIF‐67 surpasses in terms SSA, electron ion transport speed, structural stability, leading improved electrochemical performance. capacitance 1064.2 F g −1 at current density A observed 1 M H SO 4 aqueous electrolyte three‐electrode system. Subsequently, symmetric supercapacitor (SSC) constructed investigate system's capacitive behavior. Notably, SSC exhibited peak device‐specific 325.40 , 24.51 Wh kg achieved maximum power 2.4 kW . practical functionality device was demonstrated connecting two symmetrical series, effectively powering red LED. These results highlight new opportunities engineering CNO metal–organic framework‐based materials, paving way advancements future technologies.
