چکیده انگلیسی
A new material of Ce-Mg-O nanoparticle, which can be applied as catalyst support for methane combustion reaction, has been successfully synthesized and characterized by XRD, AFM, Raman and temperature-programmed reduction (TPR). The design of adding alkaline-earth metals into CeO2, the typical structure of Mg2+ enters the lattice of CeO2 to form a solid solution, whose activity for methane combustion is reasonable. The Ce-Mg-O new material supported iron catalysts are very active for methane comustion (the methane conversion reaches 90% at 560 °C). The effect of nanoparticle size and good capability of oxygen storage are also key factors affecting catalyst activity.
