Mangosteen peel-derived activated carbon for supercapacitors
文献摘要:
This work reports the effects of activation temperatures on the porous development and electrochemical per-formance of activated carbons.Herein,activated carbons were prepared from the biowaste of mangosteen peel by using KOH activation at temperatures of 400,600,and 800℃.The results demonstrate that the specific surface area increases with increasing the activation temperatures in which the well-developed porous structure after KOH activation at 800℃provides the highest specific surface area of 1039 m2 g-1.At 600℃,the activated carbon delivers the highest specific capacitance value of 182 F g-1 at a current density of 0.5 A g-1 in 3 M KOH aqueous electrolyte.This is correlated well with its high micropore fractions(99%).Moreover,it was found that the activation temperature changes the major contribution of oxygen-containing functional group on surface of activated carbon,which is beneficial for the enhancement of the specific capacitance value of activated carbon at the temperature of 600℃.This work suggests that the activation temperature is a key to optimizing the elec-trochemical performance of activated carbons.Overall,our activated carbons can be considered as a strong candidate for use as electrode materials in supercapacitors.
