主　　题：Carbon monoxide Nano perovskite Oxidation Cerium Lanthanum Strontium 

摘      要：The collection of different cations in the A and B sites of ABO3 was explored for the regularity of perovskites phase ***,Sr2？,La3？,and Ce4？are selected as the cations of site *** site B is considered to be Mn or Co *** analysis and Fourier transform infrared spectroscopy results confirm the formation of perovskite structure for catalysts in which La3？and Sr2？are considered as the cations of site *** is detected as the main crystalline phase when Ce4？is selected to be cation of site *** is found that the octahedral factor（rB/rO） takes the same important role as the tolerance factor to form cubic *** crystallite size of the products was calculated by data of the XRD and measured by the TEM *** of the XRD and TEM studies were supported by the study of the particles size distribution,which was carried out in a particle size *** perovskite samples were also used for stoichiometric oxidation of carbon monoxide with air.
