ABSTRACT A series of hybrid mesoporous MCM-41 materials containing different amino groups (such as 3-aminopropyl (AP-),(2-aminoethylamino) propyl (AAP-), or [2-(2- aminoethylamino) ethylamino] propyl (AEP-) group) were prepared by a post-grafting method, and characterized by means of X-ray powder diffraction (XRD), N 2 adsorption, Fourier transform-infrared spectroscopy (FT-IR) and temperature-programmed desorption ...
