AgY zeolite as catalyst for the selective catalytic oxidation of NH3

Ag-exchanged Y zeolites (Si/Al = 2.5; Ag/Al = 0.30–0.95) have been tested in the NH3–SCO reaction, the most promising method for the elimination of ammonia emissions, and deeply characterized before and after reaction by using a variety of techniques (XRD, TEM, UV–Vis, 109Ag NMR, XAS spectroscopies).
