Metallic Nanoparticles Adsorbed at the Pore Surface of Polymers with Various Porous Morphologies: Toward Hybrid Materials Meant for Heterogeneous Supported Catalysis
Résumé
Hybrid materials consisting of metallic nanoparticles (NPs) adsorbed on porous polymeric
supports have been the subject of intense research for many years. Such materials indeed gain from
intrinsic properties, e.g., high specific surface area, catalytic properties, porous features, etc., of both
components. Rational design of such materials is fundamental regarding the functionalization of the
support surface and thus the interactions required for the metallic NPs to be strongly immobilized
at the pore surface. Herein are presented some significant scientific contributions to this rapidly
expanding research field. This contribution will notably focus on various examples of such hybrid
systems prepared from porous polymers, whatever the morphology and size of the pores. Such
porous polymeric supports can display pores with sizes ranging from a few nanometers to hundreds
of microns while pore morphologies, such as spherical, tubular, etc., and/or open or closed, can
be obtained. These systems have allowed some catalytic molecular reactions to be successfully
undertaken, such as the reduction of nitroaromatic compounds or dyes, e.g., methylene blue and
Eosin Y, boronic acid-based C–C homocoupling reactions, but also cascade reactions consisting of
two catalytic reactions achieved in a row.
