Metal nanoparticles inside microgel/clay nanohybrids: Synthesis, characterization and catalytic efficiency in cross-coupling reactions

Poly(N-vinylcaprolactam), a comprehensive review on a thermoresponsive polymer becoming popular

“…Contin et al [209] Figure 18 summarizes the use of poly(NVCL-co-AAEM) micro/nanogels as reactors to prepare hybrid micro/nanogels filled with various nanoparticles.…”

“…NaBH 4 , ethanol, or hydrogen gas, were used as reducing agents. The resulting Pd-containing ternary microgel nanocomposites were active catalysts for the Suzuki reaction of aryl iodides in a water-rich medium[209]. An increase in the hydrodynamic radii was observed for ternary nanocomposite microgels with 15 wt% clay content (300 nm), compared to those of the original microgel/clay nanocomposites which are 100 nm for the pure microgel with 15 wt% clay content[162].…”

Cobalt and nickel nanoparticles fabricated p(NIPAM-co-MAA) microgels for catalytic applications

“…easily fix the nanoparticles within microgels. Hybrid microgels are extensively used as catalysts for the reduction of nitroarenes (4,25,41), nitriles (aliphatic and aromatic) (42) and coupling reactions (43). To the best of our knowledge, no researcher has yet studied the catalysis of p-nitrophenol (4-NP) by using Co and Ni nanoparticles fabricated in poly(N-isopropylacrylamide-co-methacrylic acid) [p(NIPAM-co-MAA)] hybrid microgels.…”

Hydrophobic superparamagnetic FePt nanoparticles in hydrophilic poly(N-vinylcaprolactam) microgels: a new multifunctional hybrid system

“…4: red dots). Detailed analysis of the sedimentation velocities for all samples (MG@FePt- [1][2][3][4][5] showed that particles of the first fraction (black cubes) have nearly the same sedimentation velocity as pure microgel (2.33 ± 0.01 µm · s -1 ).…”

“…metals [2][3][4] or metal oxides 5,6 . These kinds of microgels are three dimensional cross-linked biocompatible polymeric colloids and they gain increasing interest due to their characteristics like biocompatibility, 8 tunable size and porosity [9][10][11] as well as sensitivity to external stimuli e.g.…”
