Abstract:
In this experiment, a TiO2-Ce0.9Zr0.1O2 support with core-shell structure was successfully prepared by a precipitation method and VO /TiO2-Ce0.9Zr0.1O2 catalyst was prepared by an impregnation method, and the catalyst was used to catalyze the NH3-SCR of NO. Based on the results of HRTEM, XRD, BET, H2-TPR, NH3-TPD, XPS, Py-IR, it was speculated that due to the interaction between TiO2 and Ce0.9Zr0.1O2, more oxygen vacancies and Ce3+ are generated, which are beneficial to the existence of low-valence V by electron transfer between high valence state V and Ce3+and increase the acidic sites on the catalyst surface. The catalytic activity (>97%) of the VO /TiO2-Ce0.9Zr0.1O2 catalyst is superior to the current commercial catalyst (V2O5-WO3/TiO2) and has a higher N2 selectivity (>97.5%) at 40 000 h-1 GHSV and 250-400 °C.
