%X Ordered mesoporous carbons were synthesized by using as-synthesized MCM-48 as the template and resorcinol (R)-formaldehyde sol as the carbon precursor. By changing the molar ratio of resorcinol (R) to template (a w(R)/w(MCM-48)) and resorcinol (R) to water(w(R)/w(H2O)), mesoporous carbons with different porosities were produced. The obtained samples were characterized by N2 adsorption-desorption, X-ray diffraction, scanning electron microscopye, transmission electron microscopye and thermogravimetric analysis. It is found that the optimized a w(R)/w(MCM-48) and a w(R)/w(H2O) ratios are in the rang from a 0.50aa to a 0.65aa and froma 0.15 to 0.35, respectively, and the resulting ordered mesoporous carbons has BET specific surface areas greater than 1125m2/g, mean pore sizes from a 2.2aa to a 2.4aanm, and high thermal stability.a¤
