In this article it is described that the oxidation activity and selectivity can be well interpreted in connection with the acid-base properties of metal oxide catalysts and that the interpretation holds well for various kinds of mixed oxide catalysts and oxidation reactions.
The following subjects are dealt with ;
1) Acid-base properties of various kinds of mixed metal oxides,
2) The correlation between catalytic property and acid-base properties,
3) The role of each component in the catalytic actions of mixed oxide catalysts.
