Influence of the Oxide Support upon Different Oxidation Reactions

5 Influence of the Oxide Support upon Different Oxidation Reactions 

The above studies with methanol oxidation over the different supported vanadia catalysts demonstrated the dramatic effect of the specific oxide support on the reaction TOF, approximately four orders of magnitude for methanol oxidation. Several other oxidation reactions over the same series of supported vanadia catalysts were also investigated to determine if the effect of the oxide support is a general phenomenon, and the results are listed in Table 2. 

For all the oxidation reactions listed in Table 2, it was found that the specific oxide support had a significant effect on the oxidation reaction TOF. The methanol oxidation TOF was the most sensitive to the oxide support ( 104 factor), followed by butane oxidation 20,38 and selective catalytic reduction of NO by NH345 ( 102 factor), and oxidation of CO46 and S0247 ( 10 factor) were the least sensitive. The differences in order of magnitude of the support effect on the
