Methane gas storage in self-ordered mesoporous carbon (CMK-3)

We synthesized one kind of hexagonal mesoporous carbon (CMK-3) using hexagonal SBA-15 mesoporous silica as a template. The surface area of the CMK-3 is about 950 m2/g, and pore is uniform with a size of 3.90 nm according to the N2 isotherm curve. The amount of adsorbed methane gas is 81.35 mg/g {= 117.33 ml (STP)/g} at the high pressure 35 kg/cm2 at room temperature 298 K. The experimental results satisfy an extended Dubinin–Radushkevitch (DR) {ln N = ln NL − (ΔG/βE0)2} plot even in the mesopore range.
