Abstract: Mechanochemical activation improves sorption by supporting materials, decreases the temperature of supported nickel chloride reduction, and increases the catalytic activity of supported nickel in ethylene hydrogenation. The reason for the improvement of sorption ability is the formation of a "juvenile" surface and outcrops of crystalline structure defects. A decrease in the temperature of supported nickel chloride reduction is due to the participation of conductivity electrons of mechanochemically activated supporting materials in some elementary steps or to the strengthening of O2- anion electron-donor properties upon the mechanochemical activation of oxides. An increase in the catalytic activity can be explained by an increase in the dispersity of the supported metal and by the effect of support defects. A number of properties of catalytic systems are due to defects only.
