Double-Layer Capacitance of Carbide Derived Carbons in Sulfuric Acid

Nanoporous carbons obtained by selective leaching of Ti and Al from , as well as B from , were investigated as electrode materials in electric double-layer capacitors. Cyclic voltammetry tests were conducted in from on carbons synthesized at 600, 800, 1000, and . Results show that the structure and pore sizes can be tailored and that the optimal synthesis temperature is . Specific capacitances for CDCs and CDCs were 175 and , respectively, compared to multiwall carbon nanotubes and two types of activated carbon, measured herein to be 15, 52, and , respectively.
