Abstract

Electrodeposition of Cu on the surface of silica free rice husk activated carbon with ultrasonic irradiation aimed to increase the value of specific capacitance was carried out. Silica free rice husk activated carbon was synthesized using H3PO4  activator and extraction of silica using KOH. The surface area of rice husk carbon was obtained before and after the extraction of silica and after activation were 57.2833 m2/g, 180.5378 m2/g and 184.6074 m2/g, respectively. XRF analysis showed that Cu depositioned on the surface of silica free rice husk activated carbon and based of CV measurements showed that electrodeposition of Cu with ultrasonic irradiation can increased the value of specific capacitance. Specific capacitance of silica free rice husk activated carbon before and after electrodeposition of Cu with ultrasonic irradiation were 657.75 nF/g and 721.08 nF/g, respectively.

Abstract

A study on synthesis and characterization of nanoporous carbon derived from sugarcane bagasse   (Saccharum   officianarum)   by   ultrasonik   irradiation   using   ZnCl2     activator   for electrochemical capasitor application has been investigated. Nanoporous carbon is a basic material for the electrode in the electrochemical energy storage. Nanoporous carbon has been synthesized based on three-steps procedures, i.e. carbonization in temperature of 350 0C, silica extraction, and activation using ZnCl2  with ultrasonic irradiation. Activated carbon with irradiation showed an increasing in intensity of the –OH functional group stretch at wave number of 3419,79. The results of XRF analysis showed the highest content of oxide compound in the activated carbon was ZnO as 97,06%, and result of XRD analysis showed that activated carbon has both amorphous and crystalline. The result of SEM analysis showed that the pores evolvement of irradiated activated carbon was better than un-irradiated activated carbon, with diameter of the pores 1,5 to 2 µm. The surface area of the carbon in optimum temperature of 30 oC for 60 minutes was 171, 2802 m2/g and the energy storage capacity was 0,3284 x 10-5 F/g.
