| description | We develop new approach to produce carbon nanostructures, by using biomass as precursor, hydrothermal pretreatment and microwave pyrolysis as preparative methods. The crystallography and surface functionalities of carbon sheets were analyzed based on x-ray diffraction and FTIR data. The electrical conductivity was examined by using Kelvin methods. The electrochemical behavior tests were carried out upon binderies carbon pellet using cyclic voltammetry method of three electrodes system. FTIR analysis showed that the existence of C=C in aromatic of carbon vibration in 1100 – 1300 cm-1, carboxyl – carboxylate bonding vibration in 1600 cm-1, O-C=O and O-C=N bending vibration in 1600 – 2500 cm-1 and hydroxyl-carboxyl bond. XRD analysis showed that the hydrothermal treatment eliminated the character of the basal plane of carbon. The crystal structure of carbon was only detected for edge plane (002). The carbon has 0.039 Scm-1 of electrical conductivity. The shapes of voltammograms were relatively rectangular which meant that carbon electrode underwent dominantly non-faradaic or electrical double layer process. All voltammograms showed the existence of electrical double layer characteristic ranging from 10.3 to 23.2 mFg-1. The highest electrical current can be obtained using base electrolyte (KOH). |
