Mn-SBA15 catalysts prepared by impregnation: Influence of the manganese precursor [link]Paper  doi  abstract   bibtex   
The purpose of this study was to evaluate the effect of the precursors on the synthesis of MnO x-SBA15 catalysts. The influence of the manganese phase on the activity of catalysts in the complete oxidation of ethyl acetate was also tested. SBA15 was synthesized according to a standard method reported in the literature and manganese was introduced onto the support following an incipient wetness method using three different precursors. The catalysts were characterized by N 2 adsorption, XRD, FTIR, TPR and HAADF and HRTEM microscopy. Then, they were tested in the oxidation of ethyl acetate. The results showed on one hand that the crystalline phase of deposited MnO x depended on the precursor used for the impregnation and on the other, that the manganese oxide was deposited both on the external surface and inside the mesoporosity of the SBA15 that preserved it structure, although it lost textural properties by pore blockage. The activity of the catalysts depended on the crystalline phase, being the most active those with Mn 4+/Mn 3+ pairs. © 2011 Elsevier B.V.
