Abstract

Palladium nanoparticles were obtained by the photochemical reduction of the palladium(II) complex compounds K2[Pd(C2O4)2], [Pd(Gly)2], and [Pd(β-Ala)2] in a photolyte volume. The highest rate of formation of palladium nanoparticles in the photolyte volume is observed during the photolysis of the K2[Pd(C2O4)2] complex and the lowest—in the case of the [Pd(β-Ala)2] complex. Palladium particles obtained by the photolysis of aqueous solutions of the [Pd(β-Ala)2] and [Pd(Gly)2] complexes have the highest storage stability even in the absence of a stabilizer. When calcined in air in the presence of palladium nanocomposite particles on a CeO2 carrier, the temperature of the oxidation beginning decreases, and the weight loss of the sample (soot) increases.
