Karbonisasi Dan Aktivasi Bertingkat Menggunakan Gas Co2 Dan Uap Air Untuk Pengaktifan Elektroda Karbon Superkapasitor

---

Carbonization and integrated physical activation processes were offered as an alternative method of production of activated carbon electrodes with relatively short time, ie ± 10.5 hours. This process was started by heating of samples at room temperature up to temperature resistant of 352oC using N2 at a rate of increasing temperature of 1oC/min. This process was continued until a maximum carbonization temperature of 600oC in N2 environment at a rate of increasing temperature of 3°C/min. The physical activation from maximum carbonization temperature up to a temperature of 900oC at a rate of increasing temperature of 10 °C/min using CO2 gas for 2 hours (C2), CO2 for 3 hours (C3), physical activation using water vapor for 2 hours (H2), water vapor for 3 hours (H3 ), as well as the combined activation using CO2 gas for 2 hours and continued by water vapor for 2 hours (C2H2). Measurement of electrochemical properties of the samples was carried out by Cyclic voltammetry methods (CV).Testing of the physical properties was performed in several methods such as X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray (EDX) and Bruenuer Emmet Teller ( BET). The results for electrochemical measurement showed the specific capacitance values for each sample of C2, C3, H2, H3 and C2H2, respectively, are 89.56 F/g, 93.22 F/g, 85.00 F/g, 62.50 F/g and 72.33 F/g. XRD measurement for 2θ values in the range of 24-25o for reflecting planes of 002 and 44-47o for reflection plane of 100. EDX spectra showed the percentage of carbon was 92 %. The BET surface area for each samples consecutively are 102.72 m2/g, 90.62 m2/g, 74.30 m2/g, 121.72 m2/g and 159.16 m2/g with average pore size are in range of 1.9 nm.
