DRIFTS and NO-TPD Characterization and Catalytic Activities of CuO/TiO2/γ-Al2O3 in NO+CO Reaction
The catalytic activity in NO+CO reaction was investigated, and the structure and reductive properties of various CuO/TiO2-g-Al2O3 catalysts were characterized by means of BET, XRD, NO-TPD and DRIFTS technologies. The NO-TPD profile showed that peak temperatures of NO desorption by the 12Cu15TA were lower than that by the 15TA, and no N2 desorption species detected on 15TA, indicating that the NO decomposition activity of the catalysts was higher than that of the supports. DRIFTS analysis showed the N2O adsorption peaks appeared at 150for 12Cu15TA. And a peak for Cu+-NCO- species at 2205cm-1 was detected on 12Cu15TA.
