Synthesis and Characterization of Catalytic Property of Rare Earth Complex Oxides Dy0.5Sr1.5MO4(M = Mn, Fe, Co, Ni) with K2NiF4 Type Structure

用重稀土镝的氧化物与锶、锰、铁、钴、镍的硝酸盐为原料,制备了A_2BO_4型Dy_(0.5)Sr_(1.5)MO_4(M=Mn,Fe,Co,Ni)稀土复合氧化物,用XRD技术考察了物相,合成了K_2NiF_4型四方结构的Dy_(0.5)Sr_(1.5)MO_4,并研究了其催化性能。对结构容纳因子的适用性作了讨论。

The rare earth complex oxides Dy0.5Sr1.5MO4(M = Mn, Fe, Co, Ni) were prepared. Their crystal structures have been studied by means of X-ray diffraction technique. The complex oxides with K2NiF4 tetragonal type structure have been obtained. The catalytic property has been characterized with micro-reactor and temperature programed desorption (TPD) technique. Besides, the availability of tolerance factor(t) has been discussed.
