Nanopartikuläre Katalysatoren und neue katalytische Anwendungen auf Basis der Metalle Rhodium und Cobalt

Within this work new poly(ethyleneglycol)-stabilised nanoparticles should be synthesised and tested in various catalytic reactions, as there are hydrogenation and C-C bond forming reactions (Pauson Khand reaction PKR). Additionally an effective protocol for the separation of the catalyst from the reaction solution was set up by immobilisation of the PEG-stabilised nanoparticles on an inorganic support (SPPC, Supported Peg Phase Catalyst). Also an effective separation of the catalyst was achieved by taking advantage of the high polarity of the PEG-matrix, enabling a phase switch by decreasing the polarity of the reaction solution. The immobilised nanoparticles (SPP-catalysts) were also investigated in a continuous flow process with scCO2 as the mobile phase. Furthermore Raney Cobalt was tested within this work as an active and selective catalyst for the PKR.
