Abstract
According to Tanabe's hypothesis, a binary oxide exhibits only one acidity type or no acidity. Actually most binary oxides simultaneously exhibit Bronsted and Lewis acidities; Tanabe's hypothesis cannot explain this phenomenon. Taking into account the effects of material structure and the micro-concept of acid sites, on the basis of the Tanabe hypothesis, the author proposes a new hypothesis of micro-region acid sites regarding the surface acidity of binary oxides.
