Mo-doped Ce/GE catalysts with different loading amounts were prepared by impregnation method, which were examined as catalysts in the selective catalytic reduction of NO_x by NH₃(NH₃-SCR). Furthermore, the intrinsic mechanism of Mo-doped Ce/GE catalysts for enhancing SCR activity was preliminarily investigated. It was found that the addition of Mo can increase the ratio of n_Ce³⁺/(n_Ce³⁺+n_Ce⁴⁺), the oxygen content on the surface and the acid sites of the catalyst, thus enhancing SCR activity. Compared with 5Ce/GE and 5Mo/GE, 5Ce-5Mo/GE catalyst showed more outstanding catalytic activity. In addition, the catalyst exhibited the best activity and almost 99% conversion of NO_x at 250℃, when the loading amount is 5%. 5Ce-5Mo/GE catalyst exhibited good sulfur resistance performance.
