Strong Cation Exchange with Innocence: Synthesis and Characterization of Borate Containing Resins and Macroporous Monoliths
Strong cation-exchange resins featured
by a low loading of noncoordinating
BF<sub>3</sub><sup>–</sup> or BÂ(C<sub>6</sub>H<sub>5</sub>)<sub>3</sub><sup>–</sup> anions in styrene–divinylbenzene
matrices at various cross-linking degrees were synthesized via free-radical
bulk copolymerization with the appropriate borate monomers. The polymerization
mixture was tailored to obtain swellable materials for use as insoluble
carriers of single-site heterogeneous catalysts. The parent macroporous
monolith was also prepared for direct use in continuous flow applications
showing excellent hydrodynamic properties and high chemical and mechanical
stability. All resins were carefully characterized in the solid state,
and their ability to immobilize molecular metal complexes was demonstrated
Continuous Partial Hydrogenation Reactions by Pd@unconventional Bimodal Porous Titania Monolith Catalysts
Pd nanoparticles are immobilized by a green procedure
onto unconventional
dual porosity titania monoliths. The material is used in catalytic
continuous-flow hydrogenation reactions showing excellent efficiency,
selectivity, and durability
