摘要: Ce-incorporated MCM-41 mesoporous molecular sieves (CeMCM-41) were synthesized by microwave irradiation method from sodium silicate and ammonium cerium (IV) nitrate precursors using cetyltrimethyl bromide (CTAB) as template. The resulting samples characterized means of XRD, TEM, FT-IR, UV-Vis, XPS N2 physical adsorption, respectively. effect the Si/Ce molar ratio on textural properties CeMCM-41 was investigated. results reveal that successfully synthesized. resultant materials have specific surface areas in range 602–1,216 m2/g pore sizes ca. 2.6–2.9 nm. structural are related to amount incorporation. area volume gradually reduced content sample increased, ordering diminished.
