A facile one-step synthesis to cross-linked polymeric nanoparticles as highly active and selective catalysts for cycloaddition of CO2 to epoxides

Abstract

A very convenient one-step synthesis to cross-linked polymeric nanoparticles by conventional radical copolymerization without the addition of stabilizers or surfactants was explored. Moreover, these nanoparticles exhibited excellent stability, activity and selectivity in the cycloaddition reaction of CO(2) to epoxides and could be separated from the products easily and reused.

Brønsted Acidic Ionic Liquids Mediated Metallic Salts Catalytic System for the Chemical Fixation of Carbon Dioxide to Form Cyclic Carbonates

“…Such examples include alkali metal salts [10,11], metal oxides [12], Schiff bases [13,14], transition metal complexes [15][16][17][18][19], ion-exchange resins [20], quaternary ammonium and phosphonium salts [21][22][23][24][25][26], gold nanoparticles supported on resins [27], cross-linked polymeric nanoparticles [28] and ionic liquids [29][30][31][32][33][34][35][36][37]. Although the insertion of CO 2 into epoxides to produce five-membered carbonates has been studied extensively, there is still constant motivation for developing efficient catalysts for the chemical fixation of CO 2 .…”

Emerging Corrosion Inhibitors for Interfacial Coating

“…The authors suggested the application of such gel beads in catalysis, separation technology, and ion-exchange resins. Xiong and co-workers [73] reported a facile one-step synthetic strategy for the preparation of cross-linked polymeric nanogels by the conventional radical copolymerization of a phosphonium-based IL for use as catalysts. Recently, Rahman et al used a microfluidic method to fabricate monodisperse spherical PIL microgel beads [74].…”

The Virtuous CO2 Circle or the Three Cs: Capture, Cache, and Convert

“…Graphene oxide together with an appropriate cocatalyst was found to have high yields and reaction rates in relatively mild conditions [78,79]. Also, nanoparticles of crosslinked polymers with basic functionalities were found to improve the cyclization reaction [80][81][82]. In particular, it was found that polymer nanoparticles containing imidazolium groups were able to convert epoxides with 100% selectivity and high yields to cyclic carbonates [81].…”
