TiO2/[alpha]-Al2O3 was prepared with TiCl4 as starting material, and the catalytic activities of CuO/TiO2/[alpha]-Al2O3 were examined using a GC micro-reactor NO+CO reaction system. The catalysts, especially 12%CuO/TiO2/[alpha]-Al2O3,showed high activities in NO+CO reaction. The NO conversion temperatures(T100%) were 300C[deg]and 275C[deg]for the catalysts pretreated by air and H2, respectively. The structural and reduction properties of CuO/TiO2/[alpha]-Al2O3 catalysts were analyzed using the H2-TPR, XRD, and FT-IR methods. It was found that proper amount of TiO2 increased the CuO dispersion on TiO2/[deg]-Al2O3. The 12%CuO/TiO2/[alpha]-Al2O3 catalyst had four reduction peaks ([alpha], [beta],[gamma] , and [delta]). The [alpha] and [deg]peaks were attributed to the reductions of highly dispersed CuO and crystalline CuO on the exposed TiO2 of TiO2 / [alpha]-Al2O3, respectively. On the other hand, the [beta] and [gamma]peaks were attributed to the reductions of highly dispersed CuOand crystalline CuOon TiO2/[alpha]-Al2O3, respectively. H2-pretreated 12%CuO/15%TiO2/[alpha]-Al2O3 had a strong adsorption of NO and CO, N2O and NO2 were formed. When NO and CO were adsorbed by 12%CuO/15%TiO2/[alpha]-Al2O3 the peak temperatures of N2O absorption were 200[deg]and 150C[deg] for the catalysts pretreated by air and H2, respectively.
