Paper Title:
Structures and Catalytic Activities of LaSrCoO4 and LaSrCoO3.6F0.4 Mixed Oxides
  Abstract

The perovskite-like LaSrCoO4 and LaSrCoO3.6F0.4 mixed oxides were prepared by the polyglycol gel method, investigated by using the XRD, TEM, BET, O2-TPD and XPS methods, and used successfully for CO and C3H8 oxidization. The results indicate that LaSrCoO4 and LaSrCoO3.6F0.4 mixed oxides have K2NiF4 structure. The catalytic activity of LaSrCoO4 is better than that of LaSrCoO3.6F0.4, this is explained in terms of more mobile lattice oxygen, higher content of Co3+, more oxygen vacancies, smaller particle size and larger BET surface areas of LaSrCoO4.
