Production of activated carbon from waste coconut shell via microwave irradiation carbonization system for supercapacitor electrode / Mohd Iqbaldin Mohd Nayai

Activation process for coconut shell was done by using chemical activation method of microwave-induced KOH technique in order to reduce the production time. The activation process was successfully carried out at power level of 100 to 1000W with irradiation time and impregnation ratio of 10 to 30min...
