Preparation of biomass nanocomposite from Pampas and metal oxide nanoparticle derived metal-organic frameworks Ni-MOF as electrode materials for supercapacitor fabrication

Due to the limited fossil energy sources, in ۱۹۷۸, a group of energy sources called electrochemical capacitors, known as supercapacitors, were introduced (۱). Materials used as electrodes in electrochemical supercapacitors (ESCs) include a wide group of materials including metal oxides and hydroxides, carbon materials, conductive polymers and composite materials. Therefore, finding new materials based on desirable structures that can be compatible materials, it is necessary to be environmentally friendly and low-cost for the new generation of supercapacitors and even other energy storage devices (۲). In this regard, we presented a novel nanofiber composite, decorated with Ni -MOF oxide nanoparticles, based on Pampas as an almost universal biomass resource. To prepare the composite, Pampas is first ground and mixed with a certain amount of synthesized Ni-MOF and placed in a furnace under nitrogen gas to pyrolyze. Then, the mixtures were coated on nickel foam electrodes with an area of ۱ ۱ cm۲ by solution casting method. Finally, the electrodes were dried in an oven to obtain working electrodes. According to the preliminary electrochemical measurements that were studied, the synthesized composite as an electrode showed a high specific capacity.
