Abstract
Commercial super cross-linked polystyrene (SPS) is a promising support for creating heterogeneous catalysts designed for processes of fine organic synthesis. Results from years of studying the creation of heterogeneous Pd-, Pt-, and Ru-containing catalysts based on SPS of grades MN100 and MN270. Data are presented from characterizing SPS and catalysts based on them using a complex of physical and physicochemical means of analysis. It is shown that commercial SPS can be used to synthesize catalysts in the form of spherical grains or preliminarily ground powders. Along with the nature of a metal catalyst precursor, the form of an SPS has a strong effect on the distribution of Pd, Pt, and Ru compounds and the size of metal-containing nanoparticles formed in the polymer’s medium. The catalysts in a hydrogen flow at a temperature of 300°C on the surface chemical composition of powder MN100 samples impregnated w Pd, Pt, and Ru compounds is considered for the first time.
