| Description
| - Decane-SCR-NOx in the presence of water vapor and NO decomposition were investigated over Cu ions exchanged in ZSM-5 zeolites with various Si/Al and Al distribution. The local environment of the Cu ions in cationic sites was characterized by the combination of Si-29 MAS NMR, Vis-NIR spectroscopy of Cu(II) ions, Cu(l) Vis emission spectroscopy and UV-Vis spectroscopy of Co(II) ions as probes for the presence of Al pairs in the framework. The Cu(II) ions coordinated to four framework oxygens of the alpha- or beta-type cationic sites containing AlO-(Si-O)(2)-Al sequences represent the most active sites in decane-SCR-NOx. On contrary, the Cu(l) ions coordinated to two or three framework oxygens and located at the channel intersection adjacent to the single At atoms in the alpha- or beta-site control predominantly reaction of NO decomposition.

- Byl vyšetřován vliv Si/Al a distribuce hliníku v zeolitu ZSM-5 na SCR-NOx dekanem v přítomnosti vodní páry a rozklad NO na Cu iontech vyměněných do zeolitu. Lokální uspořádání okolí Cu iontů v kationtových polohách bylo charakterizováno pomocí kombinace 29Si MAS NMR, Vis-NIR spektroskopie Cu(II) iontů, Vis emisní spektroskopie Cu(I) iontů a UV-Vis spektroskopie Co(II) iontů jako prób přítomnosti Al párů v mřížce. Nejaktivnější centra pro SCR-NOx dekanem představují Cu(II) ionty koordinované ke čtyřem mřížkovým kyslíkům v alfa nebo beta kationtové poloze obsahující AlO-(Si-O)(2)-Al sekvence. Na druhou stranu, Cu(I) ionty koordinované ke dvou nebo třem mřížkovým kyslíkům v alfa nebo beta poloze s jedním Al atomem a lokalizované na průsečíku kanálů odpovídají za rozklad NO. (cs)
