The physical and electrochemical properties of activated carbon electrode made from pandanus tectorius

Abstract

This research focused on analyzed the effects of carbonization and activation on the physical and electrochemical properties of carbon electrode made from pandanus tectorius. Carbon electrodes were variated in four different activation types such as non activated, chemical activation, physical activation, and chemical-physical activation. The samples were carbonized at temperature of 600 °C using N2 gas. Chemical activation was using 0.8 M KOH, and physical activation was done using CO2 gas at a temperature of 850 °C for 2.5 h. The density of the carbon electrode was analyzed by measuring mass and volumes The morphology of the carbon electrode was reviewed by the Scanning Electron Microscope (SEM) method. Chemical element composition and Purity of carbon electrode was determined by Energy Dispersive X-ray (EDX). The degree of crystallinity was characterized by the X-ray Diffraction (XRD). The surface area of the carbon electrode can be evaluated based on XRD data. Electrochemical properties was evaluated using Cyclic Voltametry by testing two electrode mechanism in 1 M H2SO4 aqueous electrolyte. The activated carbon electrode based on pandanus tectorius with chemical-physical activation provides maximum surface area and maximum capacitance of 1144.82 m2g−1 and 56 Fg−1 respectively.
