A new mesosilica HPMo/SBA-15 with molybdophosphoric acid encapsulated into its framework was synthesized by adding HPMo into a sol-gel system involving hydrolysis of tetraethyl orthosilicate under the strong acidic conditions(pH<0).Its structure and physical-chemical properties were characterized by various methods,its catalytic activities were measured by the cracking of 1,3,5-triisopropylbenzene and oxidation reaction of 2,3,6-trimethylphenol.The results show that the mesosilica with molybdophosphoric aci...
