摘要：

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 calcination, have a highly dispersed MoOx/SiO2 structure, and lead to leach-resistant catalysts; with a polyoxo precursor, (NH4)(6)[Mo7O24] center dot 4H(2)O, there is a formation of MoO3 clusters and a weaker MoO3/ SiO2 interaction.
