Thermocatalytic decomposition of methane is an interesting alternative for the production of hydrogen free of CO2 emissions, since solid carbon is obtained as a co-product. However, one of the major drawbacks of this route is the fast deactivation that conventional catalysts (both metal and carbon catalysts) undergo due to their pore blockage by carbon deposits. In this work, mesoporous ordered carbons (OCMs) have been applied for the first time as methane decomposition catalysts. Synthesis of OMCs has been performed by the nanocasting technique applied to silica templates. Furfuryl alcohol and silica SBA-15 were employed in the present work as carbon precursor and hard-template, respectively. After carbon formation, the silica template was removed by dissolution in basic medium, which led to the formation of a mesostructured carbon material. The catalytic activity was evaluated using a thermobalance operating with a mixture of 10% methane-90% argon as reactive gas. Hydrogen production was indirectly measured through the weight increase of the catalyst due to carbon deposition. Two OMCs catalysts, with single and bimodal porosity, together with a commercial carbon black (reference catalyst), were evaluated. The OMC sample having a bimodal mesoporosity (30 and 50 Å) exhibited always the highest activity. This activity was much higher than that of carbon black, in spite of the latter being a very active catalyst as reported in literature, with hydrogen production rates in the range 2 – 9 L H2 / (g catalyst h). Moreover, almost no deactivation of the catalyst was detected during several hours of reaction.
