摘      要:In this paper,a new delaminated mesoporous material was prepared by swelling the lamellar phyllosilicate Magadiite using cetyltrimethylammonium bromide and tetrapropylammonium hydroxide solution,followed by delamination under the cavitation of ultrasonic *** characterization tools including XRD,N2 adsorption,NMR,IR,SEM and TEM were employed to observe its structure and *** results show that the delaminated material has no long-range crystalline ***,not only high surface area is obtained,but almost half of it is external *** observation for the morphology further reveals that it is made up of the random stacking of single or few *** these characters show that this delaminated mesoporous material meets the requirements for application as support in the hydrotreatment of heavy molecules.
