CE-CONTAINING MCM-41 MATERIALS WERE PREPARED VIA A DIRECT, NONHYDROTHERMAL METHOD AT ROOM TEMPERATURE FROM _TETRA_-ETHOXYSILANE, _N_-HEXADECYL TRIMETHYL AMMONIUM BROMIDE, AMMONIA SOLUTION, AND CERIUM(IV) AMMONIUM NITRATE PRECURSORS. COMPOSITE MATERIALS CONTAINING THE NOMINATED RATIOS OF 5 AND 10% (W/W) CEO2/MCM-41 WERE TARGETED. THE OBTAINED MATERIALS WERE INVESTIGATED BY TGA, DSC, FTIR, DIFFUSE REFLECTANCE UV–VIS, XRD, N2 ADSORPTION/DESORPTION ISOTHERMS, AND SEM. RESULTS INDICATED ... إقراء المزيد
