Investigation of the zeolitic nature of the microporosity inside the materials obtained from the hydrothermal treatment of Al-SBA-15 in the presence of the ZSM-5 template

摘要：

The 16 h - alkaline hydrothermal treatment of Al-SBA-15 in the presence of tetrapropylammonium bromide (TPABr) such as TPABr/Al < 1 led to materials bearing both mesopores and zeolite-type micropores. The combined use of hyperpolarised 129Xe NMR, - plot studies and a catalysis test gave evidences for the ZSM-5 nature of the micropores as well as some indications in favour of the connection between the different porous networks.
