The synthesis and use of nitrogen-containing copolymers for anchoring Ru(II) and Rh(I) species is described. The supported species are effective as catalysts for the decomposition of H2O2 in aqueous medium at neutral pH. The polymers as well as the supported catalysts have been characterised by physical and chemical methods. The effects of [H2O2], catalyst loading and pH of the medium on the rate of decomposition have been studied. Suitable mechanisms have been proposed to account for the kinetics. Recycling efficiencies of the catalysts are found to be good.

The decomposition of H2O2 catalyzed by polymer supported transition metal complexes

Journal of Molecular Catalysis A: Chemical

Synthesis of new hydrogel polymers based on 2-hydroxyethyl methacrylate and other functional monomers is described. These copolymers are useful for anchoring palladium and rhodium species. The resulting supported catalysts are effective for the hydrogenation of alkenes, alkynes and dienes under mild conditions. The supported catalysts have been characterised by chemical analysis, particle size measurements, IR, TGA and X-ray photoelectron spectra. Kinetics of hydrogenation have been evaluated using the concepts applicable to slurry reactors. The hydrogenation proceed through the 'unsaturate route'. Relative reactivities of a few substrates, solvent and particle size effects and selectivities by product analysis have been assessed. These catalysts possess excellent recycling efficiencies. © 1990.
