Type: article
Abstract: High specific surface area activated carbon was prepared frombamboo by chemical activation with KOH.The influenceof activation parameters on the final products was investigated by varying the KOH/bamboo ratio,activation temperature andhold ti me.The samples were characterized by nitrogen adsorptionisotherms at 77K.The specific surface area and pore volume ofactivated carbon were calculated by BET and t-plot method.The possible activation mechanism was also proposed.Under theexperi mental conditions,the opti mumconditions for preparing high specific surface area activated carbon are at a KOH/precur-sor ratio of 1.0,an activation temperature of 800℃and a hold ti me of 2h.With these experi mental conditions,an activated car-bon with a BETsurface area of 2996 m2/g and a total pore volume of 1.64cm3/g was produced.The product is a novel materialfor adsorption and for the applicationin electric double-layer capacitors.
