Towards the improvement of hydrotreatment catalysts through the encapsulation of heteropolyoxometalates inside the framework of SBA-15 silica.

Abstract : In the context of the search for higher performance hydrodesulfurization catalysts, materials made by a novel method of immobilizing heteropolyoxometalates on mesoporous oxides were compared to those derived by incipient wetness impregnation for the hydrogenation of toluene. The catalysts prepared by the one-pot encapsulation of HPMo into the walls of SBA-15 silica were found to be significantly more active for the reaction.
