Scientific grounds for the application of mechanochemistry to catalyst preparation

It is shown that mechanochemical activation is efficient in creating waste- free energy-saving methods for the preparation of hydride catalysts, hetero poly acid catalysts, and catalysts for hydrocarbon decomposition into hydro gen and carbon materials, as well for the syntheses of earlier unknown cata lytic systems. The capabilities of the mechanochemical methods are demonstr ated on modifying the catalytic properties of catalysts and supports: an in crease in the strength and catalytic activity, sorption properties, etc. Ad hesion theory applied to melts helps to describe the mechanism of mechanoch emical synthesis of catalytic systems.
