Carbon black is produced from benzene using the LPP method and applied as a conductive material in a supercapacitor. Heat treatment increases the conductivity of the carbon black, but temperatures above 1500°C decrease conductivity. The LPP-produced carbon black shows better conductive properties than Super-P, indicating its potential as a new hydrogen production method.
Carbon black is produced with H2 gas from a benzene solution using the liquid-phase precipitation (LPP) mathod. Subsequently, the carbon black is heat-treated and applied as a conductive material for a supercapacitor to evaluate its performance. Carbon black produced as primary particles by the LPP reaction aggregates and grows into a secondary structure, and then crystallizes through heat treatment to form multi-polygonal nanoshells. The electrical conductivity of carbon black increased by heat treatment, but when the temperature exceeded 1500 degrees C, the electrical conductivity rather decreased. Following heat treatment at 1500 degrees C, the electrode used as the conductive material exhibits the largest specific capacitance value and the smallest IR drop. As the carbon black produced via the LPP method exhibits better conductive properties than those of Super-P, the potential to use the present method as a new hydrogen production method is confirmed.
