چکیده انگلیسی
Dispersed CuyTi1Ox catalysts derived from Cu-Ti-CO3 layered double hydroxides (LDHs) were successfully prepared. Due to the better dispersion of active CuO phase, the optimal catalyst Cu1Ti1Ox reached a high NOx conversion of 88.9% at 200 °C, which is significantly higher than that of the control catalyst 10 wt% CuO/TiO2 (29.5%). Cu1Ti1Ox catalyst also showed improved SO2 resistance, with a very stable NOx conversion of 76.4% at 200 °C after 8 h running with 50 ppm SO2, much higher than that of 10 wt% CuO/TiO2 (3.3%). The reaction mechanism was discussed with NH3-TPD and H2-TPR analyses, which indicated that Cu1Ti1Ox has more surface acidic sites and higher redox property than 10 wt% CuO/TiO2. In all, CuyTi1Ox prepared from Cu-Ti LDH precursor can work as highly efficient and SO2 resistant low-temperature NH3-SCR catalyst for NOx removal.
