We studied In-mordenite and In-ZSM5 exchanged samples produced through high-temperature treatments of In(NO3)3 impregnated solids. The transformations suffered by the zeolitic matrix and the exchanged indium species were also studied and their catalytic behaviour evaluated. For that purpose the indium-zeolites were characterised through Fourier Transform Infrared Spectroscopy (FTIR), Si and Al Magic Angle Nuclear Magnetic Resonance Spectroscopy (Si29MASNMR and Al27MASNMR), NO Temperature Programmed Desorption (NO-TPD), Thermogravimetric Analysis and Differential Thermal Analysis (TGA-DTA) techniques, and were evaluated in the SCR of NOx reaction using methane (CH4-SCR) as reductant.3)3 impregnated solids.
