| Abstract: | The perovskite like LnSrCoO 4(Ln=La,Sm)mixed oxides were prepared by the polyglycol gel method,investigated by the XRD,BET,TEM and TPD methods,and used successfully for CO and C 3H 8 oxidation.The results indicate that LnSrCoO 4 have tetragonal K 2NiF 4 structure and good oxidative activities,and the oxidative activity of LaSrCoO 4 is better than that of SmSrCoO 4.This is explained in terms of their mobile lattice oxygen,chemisorbed oxygen and content of Co 3 . |
