The aim of the work "Activated carbon derived from rice husk by NaOH activation and its application in supercapacitor" is to prepare a low-cost, high specific surface area activated carbon with microporous and mesoporous ranges using rice husk as the raw material. The effects of activation temperature on the specific surface area, pore structure, morphology and thermal stability of the AC samples have been examined. The AC samples were proved to be excellent electrode material for supercapacitor, hence solve the disposal and pollution problems of rice husk. | This article appeared in a journal published by Elsevier.

The specific surface area of AC sample reached 2681 m2 g 1 under activation temperature of 800 1C. The AC samples were then tested as electrode material the specific capacitance of the as-prepared activated carbon electrode was found to be F g 1 using cyclic voltammetry at a scan rate of 5 mV s 1 and F g 1 at current density 1000 mA g 1 in the charge discharge mode. amp 2014 Chinese Materials Research Society.
