Conclusions
-
1.
In the conversion of isopropanol, there is a change in the selectivity of the action of all three oxides (TiO2, ZrO2, HfO2). This is especially sharply manifested on titanium dioxide.
-
2.
Titanium, zirconium, and hafnium dioxides are close in physicochemical and catalytic properties.
-
3.
A relationship is observed between the specific catalytic activity of the oxides and the structure of the d-shells of their cations.
