The development of surfactant templated methods of forming mesoporous materials provides a general pathway to extremely high surface area metal oxide catalysts and catalyst supports.  The synthesis procedures can result in highly ordered materials in a wide variety of porous geometries.  Variations on the synthesis conditions can produce hierarchically porous materials that combine ordered nanostructure with macropore networks. Such materials are particularly suitable for catalysts used in flow systems since they show considerably less pressure drop than packed particle beds and are less prone to clogging. This presentation will address the synthesis of such materials, illustrated with the synthesis of ordered arrays of 5 nm diameter Co3O4 nanorods with surface areas exceeding 120 m2/g as hierarchically porous monoliths.
