The effect of manganese and aluminum cations on the formation of the crystalline structure and catalytic properties of tungstated zirconia has been studied. It has been shown that the modification of ZrO2 with both cationic and anionic additives leads to the stabilization of its tetragonal form and the formation of substitutional solid solutions on its basis. It has been found that manganese and aluminum additives have different effects on catalytic properties in heptane isomerization.
