| Description
| - Zeolitic materials with combined micro and mesoporous structure were synthesized using two differ-ent approaches. A first series of the samples was obtained by impregnation method. Suspension of Betananoparticles was impregnated on SBA-15 mesoporous silica. In the second synthesis route, called non-templating method, Beta nanoparticles were aggregated under specified conditions with the formation ofmicro-mesoporous material (without the use of the mesopore directing agent). Micropores were presentin the zeolite nanoparticles, while mesopores were located in the interparticle space. The combinedmicro and mesoporous structure of the obtained materials, exhibiting the properties of Beta zeolite, wasconfirmed by nitrogen sorption measurements, XRD, TGA and DRIFT techniques. The hierarchical porousstructure of the samples resulted in an improved accessibility of ion-exchange positions in compari-son to conventional Beta zeolite and allowed the introduction of iron, nearly exclusively in the form ofmonomeric Fe3+cations and oligomeric FexOyspecies. The iron modified micro-mesoporous samples aswell as SBA-15 and Beta zeolite (as reference samples), were tested as catalysts of N2O decomposition.The most promising micro-mesoporous sample (Fe-Beta/meso) was tested as catalyst in the reactions ofN2O decomposition and N2O reduction with CO at different composition of gas mixture (in the presenceof O2, H2O and NO). Catalytic activity of iron-exchanged, micro-mesoporous Beta and conventional Betazeolites in the reaction of N2O conversion was very similar.
