碩士 === 國立中正大學 === 化學工程研究所 === 107 === Activated carbon (AC) is regarded as one of the most promising active materials for high performance supercapacitor (SC) owning to its high specific surface area and theoretical specific capacity. In this study, oil palm empty fruit bunch (EFB) which is the agricultural residue was employed as precursor to produce ACs which were fabricated by a series of cleaning, carbonization and chemical activation processes. The as-produced AC possesses a specific surface area of 2774 m2/g, which is very high among the AC produced from biomass materials. In order to enhance the performance of SC, the AC was modified by nitrogen doping treatment. The specific capacity of AC and nitrogen-doped AC were 182 to 215 F/g, respectively, at a current density of 0.5 A/g in 6M KOH aqueous electrolyte. We demonstrated that the agriculture waste can be processed to become activated carbon with a high specific surface area for SC application.
