In Section II the perovskite and related structures are briefly introduced. In Section III the methods most frequently used for perovskites preparation are described comparatively. Sections IV, V, and VI refer to the bulk and surface properties of perovskites. Some of these properties will facilitate understanding of the catalytic action of these compounds. Section VII includes a review of the reactions where perovskite oxides were used as catalysts. Some of them are described separately (Sections VII,A-H). These include reactions that were more extensively studied or reactions that may have an increasing interest in the near future. Section VII,I includes less studied reactions such as oxygen homomolecular exchange, hydrogen and NH3 oxidations, N20 decomposition and dehydro-... 

The dissociation of molecular nitrogen may be investigated separately by measuring the rate of the homomolecular exchange reaction (80-87)... 

Similarly, measurements of the rate of the homomolecular exchange reaction Ha + Dg = 2HD may be evaluated provided that the isotope effect resulting from a mass ratio 1 2 is taken in account. Since these reactions have been reviewed by other authors (107,108), no discussion is included in this article. 

At higher temperatures, additional pathways were suggested to be operative and it was observed that homomolecular exchange required the removal of most surface hydroxyls at high temperatures in order to proceed. In...
