Three activated carbon samples were synthesized via the template synthesis, in which a polymer was impregnated into the porous networks of zeolite Y and carbonized at three different temperatures. The carbon samples were structurally characterized and examined, respectively, for the application of energy gas (CH 4 and H 2 ) storage. It was found that (1) at high pressure end (P > 35 bar) the methane storage capacity is approximately proportional to the surface area while the hydrogen storage capacity is predominated by the volume of micropores; (2) at low pressure end (P < 1bar), however, the adsorption capacity is a strong function of the size and volume fraction of micropores/small micropores. The role of mesopore, micropore, and small micropore was discussed in details with respect to the adsorption of H 2 /CH 4 .
