Abstract: Disclosed is a simple, cheaper and green approach for low temperature synthesis of functionalized multilayer fullerene from the pure ghee (clarified butter) to obtain activated multishell graphitized non-porous fullerene in the form of nano-onions (CNOs), for fabricating high performance exohedral type of super capacitors by incorporating suitable transition metal oxide. Further, the approach relates to an exohedral type supercapacitor composite, containing non-porous CNOs and transition metal oxide nanoparticles with enhanced specific capacitance in 0.5 M H2SO4.
