Hydrogenation of o-Chloronitrobenzene over Polymer-stabilized Palladium-Platinum Bimetallic Colloidal Clusters
Hydrogenation of o-chloronitrobenzene o-CNB. has been studied in methanol at 303 K and atmospheric pressure over polyvinylpyrrolidone-stabilized palladium–platinum PVP-PdrPt. bimetallic colloidal clusters. The catalytic properties for the hydrogenation of o-CNB to o-chloroaniline o-CAN. are found to depend on the metal composition of the bimetallic
clusters. All the bimetallic clusters are mor...

The Magnetic Polymer Microsphere Stabilized Nano-Metallic Colloids as A Facilely Recoverable Catalyst
Magnetically responsive hierarchical magnetite/silica/poly(ethyleneglycol dimethacrylate-co-4-vinylpyridine) (Fe3O4/SiO2/P(EGDMA-co-VPy)) tri-layer microspheres were used as stabilizers for gold metallic nanocolloids as a facilely recoverable catalyst with the reduction of 4-nitrophenol to 4-aminophenol as a model reaction. The magnetic microsphere
stabilized gold metallic nanocolloids were prep...

Synthesis of Monodisperse Hollow Polymer Microspheres with Functional Groups by Distillation Precipitation Polymerization
Monodisperse hollow polymer microspheres having various functional groups on the shell-layer, such as carboxylic acid, pyridyl and amide, were prepared by two-stage distillation precipitation polymerization in neat acetonitrile in the absence of any stabilizer or additive, during which monodisperse poly(methacrylic acid) (PMAA) afforded from the
first-stage polymerization was utilized as the seeds...

Preparation of Narrow or Monodisperse Polymer Microspheres by Distillation-precipitation Polymerization
Narrow- or monodisperse poly(divinylbenzene-co-acrylonitrile) (poly(DVB-co-AN))
microspheres with reactive cyano group were prepared by distillation-precipitation
polymerization of divinylbenzene (DVB) and acrylonitrile (AN) in neat acetonitrile
with 2,2′-azobis(isobutyronitrile) (AIBN) as initiator in the absence of any stabilizer
or additive without stirring. The effects of the comonomer feed o...

Synthesis of Monodisperse Titania/Polymer Core-shell Hybrid Microspheres
Monodisperse titania/polymer core-shell microspheres were prepared by a two-stage reaction with titania as core and poly(ethyleneglycol dimethacrylate) (PEGDMA)
as shell, in which the titania cores were synthesized by a sol-gel method and subsequently grafted with 3-trimethoxysilyl methacrylate as the first-stage reaction to incorporate the vinyl groups on the surface of inorganic core. The PEGDMA...
