Immobilization of organocatalysts and metal nanoparticles on continuous-flow microreactors offers an efficient catalytic system that exploits and enhances the advantages of both nanocatalysis and flow chemistry, the so-called flow nanocatalysis approach. Various approaches have been developed for the development of continuous-flow reactions including immobilization and subsequent anchoring of organocatalysts and metal nanoparticles within microfluidic reactors. However, many applications of microfluidic reactor-supported catalysts are still hampered by catalysts decomposition and their subsequent leaching from the microfluidic reactor to the product stream. This dissertation focuses on the investigation of structure/property/performance relations of a new catalytic membrane reactor platform for conducting catalytic reactions in a continuous-flow fashion. More specifically, it focuses on permanent immobilization/impregnation of organic or metal nanoparticle catalysts by covalent bonding within highly swelling-resistant asymmetric polymeric hollow fiber surfaces for non-leaching catalysis.
