Nitrogen-containing microporous carbons prepared from anionic surfactant-melamine/formaldehyde composites

Nitrogen-containing microporous carbons have been synthesized by the carbonization of anionic surfactant-melamine/formaldehyde (MF) composites, which were themselves formed by an electrostatic organic–organic interaction. The carbons prepared from sodium dioctyl sulfosuccinate-MF and sodium dodecyl sulfate-MF mixtures have high surface area of 464 and 539 m2 g−1, respectively. The N/C molar ratios of the carbons are 0.11. The resultant carbons showed capacitances higher than 200 F g−1 in an acidic solution of 1 M H2SO4 at a scan rate of 1 mV s−1.
