Synthesis of Colloidal Supported Metal Nanoparticles
(CSMNs) as Intermediate Nanocatalysts
Description of Invention : We have utilized a four step process for synthesizing the palladium
nanoparticles attached to silica colloids. The four steps in this process include synthesizing the silica colloids,
synthesizing the PVP capped palladium nanoparticles, functionalizing the silica colloids, and attaching the
PVP capped palladium nanoparticles to the silica colloids.
Potential Areas of Application:
1) This invention would be very useful as intermediate nanocatalysts for liquid-phase reactions such as
cross-coupling reactions, hydrogenation reactions, and dechlorinations.
Main Advantages of Invention:
1) The CSMNs combine the advantages of heterogeneous catalysts in a near homogeneous format.
2) The CSMNs can be suspended in solution during liquid-phase reactions.
