Abstract
Commercial hyper-cross-linked polystyrene (HCLPS) was shown to be a promising support for the development of heterogeneous catalysts intended for fine organic synthesis. This paper summarizes the results of multiyear studies on the creation of heterogeneous Pd-, Ptand Ru-containing catalysts based on MN100 and MN270 HCLPS. Data obtained by characterization of HCLPS and the related catalysts using various physical and physicochemical methods are reported. It was shown that commercial HCLPS can be used in the catalyst synthesis as spherical grains or as a powder. The form of HCLPS, along with the features of the metal catalyst precursor, essentially affect the distribution of Pd, Pt and Ru compounds and the sizes of metal-containing nanoparticles formed in the polymer environment. In addition, this is the first study that considers in detail the effect of catalyst treatment in flowing hydrogen at 300 °C on the surface chemical composition of the MN100 powder samples impregnated with Pd, Pt and Ru compounds.
