Silver supported mesoporous SBA-15 as potential catalysts for SCR NOx by ethanol

Identification of the silver state in the framework of Ag-containing zeolite by XRD, FTIR, photoluminescence,109Ag NMR, EPR, DR UV-vis, TEM and XPS investigations

“…1). The very similar diffraction peaks have been reported earlier for Ag-SBA-15 obtained by direct synthesis [50].…”

Comparative studies of silver based catalysts supported on different supports for the oxidation of formaldehyde

“…Moreover, the porous structure allows the VOC molecules to reach the inner active sites to be readily oxidized. It is well known that mesoporous materials, such as MCM-41 and SBA-15, have very high surface areas and uniform pore diameter (2.0-10.0 nm), which are good for uniformly loading the catalytic active component and consequent catalytic reactions [26,27,30,31]. However, the systematic studies on the effect of the different supports on the nature of active sites and catalytic activity have seldom been reported on the Ag based catalysts for HCHO oxidation.…”

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

“…The X-ray diffraction of these two samples are presented in a prelimineray study decsribed by Boutros et al in the reference [21].…”
