The cryptomelane type oxides were prepared by the redox precipitation technique using Mn(CH 3 COO) 2 and KMnO 4 precursors. Nitrogen sorption, XRD, TEM and TPD of oxygen studies showed changes of the surface, structural and redox properties of the samples upon silver introduction. Samples were investigated in the N 2 O decomposition reaction. Direct introduction of...
