Catalytic Behaviour of Mesoporous Cobalt-Aluminum Oxides for CO Oxidation [PDF]

, 2014
Ordered mesoporous materials are promising catalyst supports due to their uniform pore size distribution, high specific surface area and pore volume, tunable pore sizes, and long-range ordering of the pore packing.
