Synthesis of Pd/C Catalysts: Approaches to Regulating the Structure of Active Sites toward Achieving High Selectivity in Hydrogenation of Organic Compounds

The methods for regulating the physicochemical and catalytic properties of Pd/C compositions by varying their synthesis conditions were reviewed. The effect of the nature of the carbon support, the composition of the palladium precursor and its reduction conditions, and the addition of a second active metal on the formation of palladium sites, their dispersion, electronic state, and catalytic properties in practically important hydrogenation reactions was demonstrated using the results obtained by the authors. These data may be useful for the development of Pd/C catalysts exhibiting high activity and selectivity in the hydrogenation reactions of polyfunctional organic compounds.
