Abstract:
A simple method for preparation of Pd catalysts supported on low-surface-area inorganic powders as
carbons, oxides (SiO2, diatomites, WO3, Ta2O5, Nb2O5, V2O5, TiO2, CeO2, ZrO2, Ga2O3, In2O3, Cr2O3, Fe2O3,
Al2O3) and salts (CaF2, BaSO4, Ca3(PO4)2) was developed. It implies hydrolytic deposition of Pd(II) precursors
onto a support in basic solutions. Regularities of the hydrolysis process without and in the presence
ofthe support are studied by various physicochemical methods. A scheme ofthe formation of catalytically
active component was put forward. Reduced with H2 at 50–120 ◦C, the palladium catalysts demonstrate
strong dependence of their specific activity in hydrogenation of aqueous maleic acid on the support
nature. TOF value for palladium nanoparticles supported onto an oxide surface slows down with increasing
polarizing ability of cations in the lattice of the oxide, that testifies to the influence of the electrostatic
field intensity at the support surface on the reaction rate
