| 英文摘要 | Flame spray pyrolysis (FSP) was utilized to synthesize Ce-Mn oxides in one step for catalytic oxidation of benzene. Cerium acetate and manganese acetate were used as precursors. The materials synthesized were characterized using X-ray diffraction (XRD), N-2 adsorption, X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), Raman spectroscopy, and H-2-temperature programmed reduction (H-2-TPR) and their benzene catalytic oxidation behavior was evaluated. Mn ions were evidenced in multiple chemical states. Crystalline Ce-Mn oxides consist of particles with size <40 nm and specific surface areas (SSA) of 20-50 m(2)/g. Raman spectrums and H-2-TPR results indicated the interaction between cerium and manganese oxides. Flame-made 12.5%-Ce-Mn oxide exhibited excellent catalytic activity at relatively low temperatures (T95 about 260 degrees C) compared to other Ce-Mn oxides with different ceriumto-manganese ratios. Redox mechanism and strong interaction conform to structure analysis that Ce-Mn strong interaction formed during the high temperature flame process and the results were used to explain catalytic oxidation of benzene.(C) 2013 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences.
