In recent years, exploitation of biomass as an economical and environmentally friendly source for the production of energy to power supercapacitor devices has gained momentum. It is a viable alternative to current methods of energy consumption and chemical production, offering a more cost-effective and sustainable solution. Additionally, biomass has an inherently high energy capacity, making it a promising source of energy for the production of supercapacitor devices. The current investigation utilizes Spathodea campanulata leaves and flowers to synthesize KOH-activated carbon (AC) through microwave approach. In this study, two types of biomass-derived materials, AC-SPL and AC-SPF, were evaluated for their suitability as electrode materials for supercapacitors. FTIR results suggested the presence of O- and N- functionalities in the synthesized carbon materials. XRD results reflected an amorphous structure with an increased crystalline size due to KOH activation. The specific capacitance values of AC-SPF were found to be 9.2F/g while for AC-SPL 6.03 F/g. The investigated samples were found to possess good physicochemical properties and promising electrochemical performance, making them suitable for use in the development of an inexpensive and eco-friendly electrode material for supercapacitor applications.
