Comparison of the conventional impregnation method using ammonium heptamolydate with a simple route to silica-supported molybdenum(VI) materials.

Résumé

Silica-supported molybdenum oxide materials have been prepared by using the ability of molybdenum oxoperoxo complexes to interact with the surface hydroxyl groups of the support, which after calcinations, have a highly dispersed MoOx/SiO2 structure, and lead to leach-resistant catalysts; with a polyoxo precursor, (NH4)6[Mo7O24].4H2O, there is a formation of MoO3 clusters and a weaker MoO3/SiO2 interaction.
