摘要

The effects of activation temperature on the electrochemical capacitance of activated carbon nanotubes (ACNT) have been investigated. The modification of activation temperature can greatly affect the ACNT electrochemical capacitance, which carries out by virtue of its effects on the ACNT Brunauer-Emmett-Teller (BET) specific surface area and graphitized degree. When the activation temperature is below 1123 K with an activation time of 1 h, the effect of the ACNT BET specific surface area on its electrochemical capacitance dominates, and the electrochemical capacitance of ACNT increases with increasing the BET specific surface area. Otherwise, the effect of the ACNT graphitized degree on its electrochemical capacitance dominates, the ACNT electrochemical capacitance decreases with increasing the graphitized degree.
