Tasi, Krisztian Niesz, Gabor Somorjai, Imre Kiricsi] The primary objective of this paper is the complete characterization of Pt/SBA-15 catalysts prepared by sonication aided impregnation. During the experiments (i) the influence of sonication applied for introducing the already prepared platinum nanoparticles into the pores of the silica support, (ii) the pressure used for preparing the tablets and/or wafers for catalytic test, (iii) the temperature of heat treatment on the structural changes of catalyst samples, (iv) the effect of platinum particle concentration, and (v) the removal of rest organic matter from the catalysts by different procedures were systematically studied. The samples were characterized by nitrogen adsorption/desorption measurements (BET), TEM, SAXS, XRD and IR. The catalytic activity of the samples was also investigated in the reaction of cyclohexene hydrogenation.
