The good catalytic performances were obtained on those catalysts supported by SiO_2. With the increasing calcination temperature from 300℃to 700℃, Co_3O_4 particles augmented and sintered on the samples surface which contained 10 wt.% cobalt, the crystallite size of Co_3O_4 was aggrandized from 7.2 nm to 20.3 nm by inchmeal. On the other hand, the activation energy for the combustion reaction was increased linearly with the augment of average crystallite size of Co_3O_4, the TOF value on prepared catalyst was decreased with it. Thus, the catalytic combustion was a typical structure-sensitive reaction.
