Tentative Summary of the Acid-Base Properties of Binary Metal Oxides... 

Ai and associates reported that for several oxidation reactions catalyzed by binary and ternary metal oxide catalysts, the catalytic activity and selectivity are correlated with the acid-base properties of the catalysts. The correlations were explained... 

Bulk and supported mixed oxide compositions, from binary metal oxides to quaternary metal oxides, consist in general of large crystalline phases possessing low surface area values (typically from 1 to 10m g ). Examples of oxides of this type of catalytic relevance are V-Nb-0, Mo-Nb-O, Co-Ti-0, Ni-Ti-0, etc. The acid-base properties of mixed metal oxides have been found to change with the nature of the constituents and their relative concentrations, preparation (co-precipitation and sol-gel synthesis among are the most popular methods used), and pre-treatments procedures. Appropriately choosing the mentioned variables, mixed oxides can be used to prepare catalysts with the desired-acid-base characteristics.

In order to prove/check the consistency of experimental data obtained in PT and CT, the principle of triads , raised first time elsewhere,will be presented in extended versions, with D and T as mixed-solvent systems, containing also some modifying agent Z, introdnced intentionally, in order to extend the pH-range covered by experimental points, obtained in PT and CT. These modifications were introduced to extend the possibilities offered by the new method of gaining a physicochemical knowledge on acid-base properties of some (mono- and polyprotic) acids in binary-solvent media. 

Discuss general trends in the bonding and acid-base properties of the binary oxides formed by the second-period and third-period elements. 

Other important uses of stannic oxide are as a putty powder for polishing marble, granite, glass, and plastic lenses and as a catalyst. The most widely used heterogeneous tin catalysts are those based on binary oxide systems with stannic oxide for use in organic oxidation reactions. The tin—antimony oxide system is particularly selective in the oxidation and ammoxidation of propylene to acrolein, acryHc acid, and acrylonitrile. Research has been conducted for many years on the catalytic properties of stannic oxide and its effectiveness in catalyzing the oxidation of carbon monoxide at below 150°C has been described (25).
