Abstract
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 m 2/g, and pore is uniform with a size of 3.90 nm according to the N 2 isotherm curve. The amount of adsorbed methane gas is 81.35 mg/g {= 117.33 ml (STP)/g} at the high pressure 35 kg/cm 2 at room temperature 298 K. The experimental results satisfy an extended Dubinin-Radushkevitch (DR) {ln N = ln N L - (ΔG/βE 0) 2} plot even in the mesopore range.
