Solvent-free selective oxidation of toluene with O2 catalysed by anion modified mesoporous mixed oxides with high thermal stability

The anion modified mixed metal oxides were active in the selective catalytic oxidation of toluene. Especially the iodine modified mesoporous mixed oxides exhibited the highest toluene conversion of 15.5% with 100% of the selectivity to benzaldehyde. This could be attributed to the strong stabilizing effect of iodide ion on the mesoporous structure of mixed oxides even at high temperatures of 1073 K.60
