The work reports the effects of the grinding treatment of Cu, Zn and Ni hydroxocarbonates, which can be used as the catalysts for organic processes. The mechano-chemical activation could be a technology of catalyst syntheses environmentally friendly, with a low energy consumption. The effects of grinding were followed by the phase analysis of solid products based on the thermogravimetry and X-ray diffraction methods.

The mechanochemical activation of solids of interest as an alternative method of inducing physico-chemical alterations in the surface and bulk properties of materials. In this review it has been shown several possible ways in which mechanical energy can initiate topochemical reactions towards multicomponent catalyst syntheses. A number of practical examples of mechanically activated systems are considereb. Some of these are: Al2O3, Fe2O3, ZnO-CrO4.
