“…Actually, the high reactivity of the catalytic membrane favors the chemoselectivity of the process. Interests on catalytic membranes have recently aroused [40,41] but the reaction times of those membranes for Suzuki coupling reactions are in the order of hours and catalyst leaching is produced. Our catalytic membrane herein reported is so efficient that the reaction is complete within seconds.…”

International audienceThe elaboration of a polymeric catalytic membrane containing palladium nanoparticles is presented. The membrane was prepared using a photo-grafting process with imidazolium-based ionic liquid monomers as modifying agent and microPES® as support membrane. Ionic liquid serves as a stabilizer and immobilizer for the catalytic species, i.e. palladium nanoparticles. The Suzuki–Miyaura cross-coupling reaction was carried out on the catalytic membrane in flow-through configuration. Complete conversion was achieved in 10 s through one single filtration, without formation of byproducts. The apparent reaction rate constant was three orders of magnitude greater than in a batch reactor. No catalyst leaching was detected. This membrane offers the possibility of continuous production with no need for a separation step of the catalyst from the reaction medium

“…Hariprasad and Radhakrishnan fabricated a dip catalyst based on a multilayer Pd–PVA thin film, which had high efficiency and reusability . Another type of dip catalyst where Pd nanoparticles were dispersed in the cellulose acetate was fabricated, which was utilized for the Suzuki–Miyaura cross‐coupling reactions in aqueous media . In another report, bimetallic nanoparticles (Ag–Pd) embedded in the polymer films were also developed and utilized as the efficient dip catalysts .…”

Dip catalysts suitable for catalyzing important chemical reactions are designed based on bioinspiration principles and are fabricated using a facile soft lithography technique. Specifically, in this work, leaves from two different plants, Gladiolus dalenii and Amaryllis belladonna are chosen, due to their contrasting surface topographical features. The surface microstructures of these two leaves are replicated on a polymer in order to prepare scaffolds for the fabrication of dip catalysts. The microstructures of these scaffolds are utilized to direct the self‐assembly of Pd nanoparticles according to the surface topographical features. A thin film of polyvinyl alcohol is used to lock the nanoparticles on the surface and prevent them from leaching. The fabricated bioinspired dip catalysts are thoroughly characterized and are demonstrated to be highly efficient for Suzuki–Miyaura cross‐coupling reactions, examined under different experimental conditions. These bioinspired dip catalysts' performance is evaluated based on the percentage yields of the reaction and is correlated with the corresponding surface topographical features to understand the effect of the scaffold architecture on the performance of the catalysts. The developed strategy can be easily adopted to fabricate many more dip catalysts, with intriguing surface features, suitable for catalyzing several other chemical reactions as well.

“…More recently, catalytic polymeric membranes, which were less studied than inorganic ones, have attracted growing interest because of their relatively low cost and high efficiency . They were found catalytically active on a variety of reactions (e.g., alcohol and ether syntheses, C‐C cross‐couplings hydrogenations, chemical reductions). Some polymeric catalytic membranes even gave full conversion of substrates within residence time of seconds, showing prospective potential of the catalytic polymeric membranes containing palladium nanoparticles (PdNPs).…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao. A polymeric catalytic membrane was previously prepared that showed remarkable efficiency for Suzuki-Miyaura C-C cross-coupling in a flow-through configuration. A mathematic model was developed and fitted to the experimental data to understand the significant apparent reaction rate increase exhibited by the catalytic membrane reactor compared to the catalytic system under batch reaction conditions. It appears that the high palladium nanoparticles concentration inside the membrane is mainly responsible for the high apparent reaction rate achieved. In addition, the best performance of the catalytic membrane could be achieved only in the forced flow-through configuration, that, conditions permitting to the reactants be brought to the catalytic membrane by convection.
