Mesoporous cobalt oxides were prepared by an inverse micelle method and calcined at different temperatures. These materials exhibited superior activity for oxidation of 2-propanol as the model substrate for VOC elimination. Highest active Co₃O₄-350 material showed a maximum turnover frequency of 25.8 h^-1 at 160 °C at a weight hourly space velocity of 60 L g^-1 h^-1. The apparent activation energies of mesoporous cobalt oxides ranged from 69.7 kJ/mol to 115.6 kJ/mol. In situ Diffuse Reflectance Infrared spectroscopy (DRIFTS) revealed that the reaction involves formation of carbonyl and carbonate species on the surface of the catalyst before complete oxidation to CO₂ and H₂O. The activities of the materials were correlated to better low temperature reducibility, large pore volumes, higher Co³⁺/ Co²⁺ ratios, and higher number of surface-active oxygen species.
