摘 要: 通过高温固相法制备不同负载量的Fe-Mn/ETS-10催化剂，利用X射线衍射仪(XRD)、傅里叶红外仪(IR)、扫描电子显微镜(SEM)、X射线光电子能谱分析(XPS)等对催化剂进行表征，考察了不同负载量对Mn-Fe/ETS-10形貌、结构组成、以及选择性催化还原(SCR)性能的影响。结果表明：Fe-Mn/ETS-10催化剂具有良好的均一性和分散性，并保持ETS-10原有形貌、晶型；5%Fe-1%Mn/ETS-10具有更多的活性位和更高的脱硝性能。CO-SCR催化性能测试结果显示，5%Fe-1%Mn/ETS-10在脱硝温度300 ℃和400 ℃时脱硝率分别达到80%和85%；最佳的Fe-Mn/ETS-10催化剂负载比(5%Fe-1%Mn/ETS-10)可以提高SCR反应的催化活性。

Abstract:Fe-Mn/ETS-10 catalysts with various compositions were synthesized by high temperature solid state reaction. These catalysts were characterized by X-ray diffractometry(XRD), Fourier transform infrared spectroscopy(IR), scanning electron microscopy(SEM) and X-ray photoelectron spectroscopy(XPS). The effect of different amounts of Fe-Mn/ETS-10 on the morphology, composition and the catalytic reduction performance was studied. The results show that Fe-Mn/ETS-10 has good uniformity and dispersion, the morphology and crystal structure of ETS-10 are kept. 5%Fe-1%Mn/ETS-10 has more active sites and higher deNOx performance. The catalysts activity of CO-SCR results show that denitrification rates of 5%Fe-1%Mn/ETS-10 are 80% and 85% at 300 ℃ and 400 ℃, respectively. So, it is concluded that an optimal Fe-Mn/ETS-10 catalyst support ratio (5%Fe-1%Mn/ETS-10) enhances the catalytic activity in the selective catalytic reduction reaction.
