Conclusions
-
1.
It may be concluded on the basis of the IR spectra obtained that the adsorption of mixtures of acetone with oxygen is accompanied by a number of chemical conversions on the surface of NiO, which leads to “hyperadditivity” in the case of adsorption.
-
2.
The nature of the surface compounds formed during adsorption depends upon the order of admission of the components of the mixture.
-
3.
The adsorption of a mixture of acetone and oxygen is characterized by the formation of enolate and molecular complexes of acetone, coordination-bonded water, and a surface carboxyl ion.
-
4.
The process of formation of surface complexes at room temperature is of a “dead end” nature.
-
5.
The greatest intensity of chemical conversions on the surface of NiO in the case of simultaneous adsorption of acetone and oxygen may be explained by the “presorption effect.”
