Poly(N-isopropylacrylamide)-grafted silica as a support of platinum colloids: Preparation method, characterization, and catalytic properties in hydrogenation

Preparation and characterization of thermosensitive polymers grafted onto silica-coated iron oxide nanoparticles

“…It is clear that there are two additional characteristic peaks for the specimens of PNIPAM grafted onto SiO 2 /Fe 3 O 4 nanoparticles. These characteristic peaks at 1650 and 1540 cm −1 are attributed to secondary amide C=O stretching and secondary amide N-H stretching of PNIPAM chains, which are consistent with previous investigations [27][28][29]. There is little trace of these adsorption peaks in the FT-IR spectrum of SiO 2 /Fe 3 O 4 nanoparticles (curve b in Fig.…”

Preparation and use of hybrid organic–inorganic catalysts

“…An alternative way for the immobilization of a hydrogenation catalyst was chosen by Suzuki et al (114). Here, the catalytically active platinum colloids were supported on poly(N-isopropylacrylamide), which in turn had been fixed to the surface of amorphous silica by means of functionalizing the surface with a radical initiator.…”

Synthesis, characterization, and heterogeneous catalysis of polymer‐supported poly(propyleneimine) dendrimer stabilized gold nanoparticle catalyst

“…Many solid support materials viz., inorganic and organic have been utilized for the immobilization of metal NPs. The commonly used inorganic support materials such as carbon,4 silica,5 alumina,6 and metal oxides7 and few organic support materials such as polystyrene matrices8–11 have been already exploited sufficiently. The insoluble functional polymer matrix with different functional groups on their surface has been used for different applications.…”
