Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 6. (a) NO conversion over the prepared catalysts. Operando XAFS collected during SCR process at temperatures of 100, 125, 150, 175 and 200 ◦C for (b) Cu-LSX- Cl and (c) Cu-LSX-Ref. (d) TEM images and elemental mapping of copper in ion-exchanged zeolites; inset: corresponding Cu species diameter distribution in the zeolites. Cu 2p XPS spectra of Cu-LSX-Cl and Cu-LSX-Ref (e) before and (f) after catalytic evaluation.
