DeNO(x) na sitach molekularnych zawierających miedź. Cz.1. Fizykochemiczna charakterystyka katalizatorów

Since 1986 when Iwamoto and coworkers discovered a very high activity of Cu-ZSM-5 zeolites in NO decomposition a huge number of papers has been devoted to various copper - containing catalysts. This review paper sums up the results presented in so far published articles concerning physico-chemical properties of micro- and mesoporous molecular sieves modified with copper. Cu-ZSM-5 is the most frequently studied zeolite and Cu-AlMCM-41 belongs to the most frequently studied mesoporous materials. Therefore, in this paper a short characteristic of ZSM-5 and MCM-41 molecular sieves is performed, as well as the precise data from FTIR, ESR and H2-TPR studies applied to the characterisation of Cu-state on the catalyst surface are presented (the Cu-species have been identified on the basis of these data).
