Abstract

Following the development of purely mesoporous templated silicas, it is a desirable next step to create innovative catalytic support materials, consisting of a stable composite matrix with combined micro- and mesoporosities and a sufficient stability to withstand most industrial treatments.We show in this paper the development of a hexagonal plugged material, with combined micro- and mesopores and a tunable amount of both open and inkbottle mesopores. The ratios of these different pore types are variable in a wide range. The obtained materials are much more stable than the conventional micellar templated structures known so far.
