Mechanochemical Synthesis of a Hydrogenation Catalyst from Nickel Oxide and Silica Gel.

For the first time, silica gel-supported nickel hydrogenation catalyst has been synthesized via the mechanochemical method from oxides in a single stage. A set of data on the effect of the catalyst mechanochemical activation conditions on specific surface area, pore size distribution, crystallites size, and crystal lattice imperfection has been obtained. Activity of the obtained catalyst towards mild-conditions reduction of multiple carbon bonds in styrene, prop-2-en-1-ol, and diethyl maleate has been studied. Recommendations for establishing the optimal parameters for obtaining a nickel catalyst using mechanochemical synthesis have been elaborated. [ABSTRACT FROM AUTHOR]
