Effect of the synthetic parameters on the textural properties of one-pot mesoporous Al–Ce–Cu systems

Various samples of the Al–Ce–Cu ordered mesoporous oxide system were prepared by a single-step synthesis using n-propanol as solvent, aluminum sec-butoxide as Al precursor, metal stearates and/or metal nitrates as Cu and Ce sources. Different reagent types and reagents ratios were used in order to explore the role of these synthetic parameters in determining the chemical, textural and structural properties of the resulting materials. The study was carried out using nitrogen physisorption at 77 K, X-ray powder diffraction (XRPD), temperature-programmed reduction (H2-TPR), temperature-programmed desorption of ammonia (NH3-TPD) and FT-IR spectroscopy of adsorbed pyridine.
