Metallic Nanoparticles Adsorbed at the Pore Surface of Polymers with Various Porous Morphologies: Toward Hybrid Materials Meant for Heterogeneous Supported Catalysis

International audienceHybrid materials consisting of metallic nanoparticles (NPs) adsorbed on porous polymericsupports have been the subject of intense research for many years. Such materials indeed gain fromintrinsic properties, e.g., high specific surface area, catalytic properties, porous features, etc., of bothcomponents. Rational design of such materials is fundamental regarding the functionalization of thesupport surface and thus the interactions required for the metallic NPs to be strongly immobilizedat the pore surface. Herein are presented some significant scientific contributions to this rapidlyexpanding research field. This contribution will notably focus on various examples of such hybridsystems prepared from porous polymers, whatever the morphology and size of the pores. Suchporous polymeric supports can display pores with sizes ranging from a few nanometers to hundredsof microns while pore morphologies, such as spherical, tubular, etc., and/or open or closed, canbe obtained. These systems have allowed some catalytic molecular reactions to be successfullyundertaken, such as the reduction of nitroaromatic compounds or dyes, e.g., methylene blue andEosin Y, boronic acid-based C–C homocoupling reactions, but also cascade reactions consisting oftwo catalytic reactions achieved in a row
