| dc.description.abstract | In order to meet the growing energy demand, effective energy storage devices are essential. Harro is a novel and bio-based precursor for the preparation of activated carbon (AC). In energy storage technologies, activated carbon is applied as an electrode material. By utilizing phosphoric acid as the activating agent, study examined at how the carbonization temperature affected the pore structure and surface chemistry of activated carbon from Harro seed stone. The AC was prepared at various temperatures such as 4000C, 5000C, 6000C and 7000C i.e.HS4, HS5, HS6 and HS7. By using FT-IR, XRD, SEM, Surface area, Total pore volume, Iodine number, Micropore volume, Methylene blue number and Raman Spectroscopy, study examined the physiochemical characteristics of the synthesized AC. Using cyclic voltammetry, the synthesized AC's electrochemical performance was examined. Results showed that, the activated carbon at 4000C has the greater surface area, Iodine number and Micropore volume of 977.19 m2/g, 960.45 mg/g and 0.69 cm3/g respectively. And the activated carbon at 7000C has highest value of Methylene blue number and specific capacitance of 334.72mg/g and 9.26× 10-3 Fcm-1 respectively. | en_US |
