Implication

Experimental study demonstrates high pseudocapacitive charge storage in nitrogen-doped carbon electrodes, indicating that proton-nitrogen interactions significantly enhance capacitance.

Key Points

To synthesize nitrogen-enriched carbon materials from melamine and evaluate their structural porosity and electrochemical capacitive performance in supercapacitor electrodes.
Polymerized melamine in mica interlayer spaces, with select samples stabilized at 250 °C for 4 hours prior to carbonization at temperatures between 650 and 1000 °C.
Characterized chemical composition, edge nitrogen sites, and porosity using elemental analysis, X-ray photoelectron spectroscopy, and nitrogen adsorption/desorption.
Evaluated electrode capacitive behavior across both acidic (1 M sulfuric acid) and neutral (3 M sodium chloride) electrolytes.
Electrodes carbonized at 750 °C achieved a peak gravimetric specific capacitance of 204.8 F g⁻¹ in 1 M sulfuric acid.
Stabilized carbons displayed higher area-normalized capacitance than nonstabilized counterparts, reaching up to 3.66 F m⁻² for samples carbonized at 1000 °C.
Capacitance decreased and scaled primarily with surface area in neutral 3 M NaCl, verifying that high capacitance in sulfuric acid arises from pseudocapacitive interactions between edge nitrogen species and protons.
