Design and Synthesis of Hybrid Materials Based on Porous Polymers and Metallic Nanoparticles by In-Situ Reduction of Metallic Salts

摘要

INTRODUCTION Considering their low-cost production, porous polymeric materials represent interesting potential candidates as insertion scaffolds for metallic nanoparticles (Au, Rh, Pd, Ag, Mg) or nanoalloys. Mainly due to nanoconfinement within the host polymeric matrices, metallic nanoparticles have already shown some very interesting properties,~1 especially regarding gas storage (e.g. hydrogen storage) and their further release.~2. In this context, investigations towards the preparation of this kind of materials have been developed via the in-situ reduction of metallic salts in the presence of well-defined nanoporous polymeric matrices, i.e. porous polystyrene~3 (PS) or highly cross-linked porous poly(glycidyl methacrylate-co-trimethylolpropane trimethacrylate)~4 (PGMA), that were suitably functionalized with either carboxylic acid or amino groups.
