TPR, XRD, N2-BET, XPS, FTIR and UV–vis spectroscopy were used for characterizing the samples. Well-dispersed cobalt oxide-like species and isolated Co2+ ions in charge compensation positions were found in the zeolite. Catalysts prepared using a single step cation exchange method showed high activity for N2O decomposition in a temperature range 300–550°C, in the presence of 0–5% O2, and high stability in the presence of 10% H2O to the feed. UV–vis spectra and TPR experiments indicated the presence of some cobalt oxides, not detected by DRX, in a Co-ZSM-5 catalyst containing 3.76 wt% Co, prepared by a solid-state reaction procedure. The N2O conversion over this catalyst was strongly affected by addition of both O2 and H2O to the feed.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-25T11:54:06Z No. of bitstreams: 1 Cruz.pdf: 224995 bytes, checksum: f65e915fcf33b82e9b11caf51987bea0 (MD5)Made available in DSpace on 2013-01-25T11:54:06Z (GMT).
