Mesostructured or Alumina-mesostructured Silica SBA-16 as Potential Support for NOx Reduction and Ethanol Oxidation

Résumé

Synthesis of some meso-structured SiO2 or aluminosilica (SBA-16 and Al-SBA-16) with a 3-dimensional cubic structure is reported. Structural and porosity properties of these materials were studied by x-ray diffraction, N2 sorption, and transmission electron microscopy imaging.; Al insertion was detd. by 27Al-MAS-NMR and acidic properties were characterized by pyridine adsorption followed by Fourier transform IR spectroscopy. These solids were tested for the selective catalytic redn. of NOx by ethanol in the presence of O2. Compared to hexagonal meso-porous SiO2 or aluminosilica (SBA-15 and Al-SBA-15), SBA-16 type materials (SBA-16 and Al-SBA-16) could be used as a potential catalyst for the oxidn. reaction; the SBA-16 solid had higher catalytic activity for NOx redn. to N2 at high temp.
