EnglishIn the present work, we compare the catalytic behaviour, in the dry reforming of methane, of Ni-based Silicalite-1 type catalyst obtained by different post-synthesis treatments. The Silicalite-1 type material, used as Ni-support, has been treated in order to observe the role of the silanol groups on the Ni impregnation, and then on the overall catalyst performance. Among the applied treatments (ionic-exchange, calcinations and silylation), the silylation is the one that allows the formation of smaller and more reducible Ni-oxide species that not only improve the methane conversion but also reduce the deactivation of the catalyst, due to the coke deposition.
