CO hydrogenation of syngas derived from the reforming reaction of natural (or shale) gas has been largely investigated for the production of useful petrochemicals such as methanol, dimethyl ether (DME) and clean fuels. To overcome the typical aggregation of impregnated active metals on the irreducible metal oxide supports, we developed new catalytic system having a highly ordered mesoporous structures such as mesoporous Co3O4 or alumina through a simple nanocasting method. Using the ordered mesoporous catalysts, CO hydrogenation reactions such as Fischer-Tropsch synthesis (FTS) and direct dimethyl ether (DME) synthesis reaction were separately investigated to stabilize the ordered mesoporous Co3O4 structures and to confirm the effects of spatially confinement of copper nanoparticles. |
