Název v původním jazyce

Nanoclustered Palladium(0) Supported on a Gel-Type Poly-acrylonitrile?N,N-dimethylacrylamide?ethylenedimethacrylate Resin: Nanostructural Aspects and Catalytic Behaviour.

Popis výsledku v původním jazyce

Gel-type resin poly-acrylonitrile (30 mol%)?N,N-dimethylacrylamide (66 mol%)?ethylenedimethacrylate (4 mol%) (ADE) is obtained in very high yield with ?-rays-sustained polymerisation in mass. Water-swollen ADE microparticles react readily with [PdCl42-]in water to give a macromolecular complex likely to be . The material undergoes facile reduction to a Pd0/ADE nanocomposite, in which a surprisingly non-homogeneous distribution of Pd0 nanoclusters suggests a remarkable inhomogeneity in the distributionof the ?CN groups through the polymer framework. This circumstance is attributed to a marked occurrence of a block-type polymerisation of the acrylonitrile leading to spheroidal domains that are particularly rich in ?CN functionalities. Pd0/ADE appears to be an active, re-usable, mechanically and chemically stable catalyst in the model hydrogenation reaction of cyclohexene in methanol under moderate conditions, carried out in batch reactors.
