摘要: Catalytic reduction of nitric oxide with ammonia was studied over transition metal ion exchanged Y zeolites (MeY). Among various catalysts used, Cu(II)Y found to be particular interest, exhibiting low temperature activity coupled an unusual activity-temperature profile. In the binary systems, where one component ions fixed as Cu(II), promoting effects second ionic species were observed. This seems correlated oxidation potential ion. Both NH3 and NO adsorbed considerably on Cu(II)Y, suggesting that NONH3 reaction proceeds between molecules. Further, from measurement kinetics, mechanism proposed a Langmuir-Hinshelwood type coordinated Cu(II) ions.
