摘要

A novel MnO_x-CeO₂ catalyst with shell-in-shell microsphere structure was successfully prepared by a one-step hydrothermal method for the first time. The obtained catalyst was characterized by SEM, TEM, XRD, N₂ adsorption and desorption, XPS, H₂-TPR and NH₃-TPD in detail, and its catalytic activity was investigated by selective catalytic reduction of NO_x with NH₃. The results showed that the MnO_x-CeO₂ microsphere catalyst presented high catalytic activity at low temperatures (lower than 210 °C), which was much superior to the counterpart MnO_x-CeO₂ catalyst without shell-in-shell microsphere structure prepared by co-precipitation method.
