Catalytic properties of Ag/Al2O3 catalysts for lean NOx reduction processes and characterisation of active silver species [link]Paper  abstract   bibtex   
A study of the lean NOx reduction activity employing different reductants over Ag/Al2O3 samples prepared from reverse microemulsions or impregnation with EDTA-complexes was carried out. A multitechnique approach was employed for characterization of the samples and/or processes taking place in the course of the NOx-SCR reaction with propylene and propane. In agreement with previous reports, the higher activity of samples with intermediate Ag loadings with samples prepared from silver-EDTA complexes presented slightly higher overall activities for the selective process. The main path for propylene activation was in the formation of acrylate-type species. The nature of Ag sites active for the SCR process was related to well dispersed silver aluminate-like phases with tetrahedral local symmetry and a relatively high disorder in the oxygen first shell.
