“…[99] Recent catalytic applications include hydrogenation and C-C coupling in water, [97] organic solvents, [100] biphasic fluorous solvents [95] and supercritical CO 2 . [101] Pd DENPs are efficient hydrogenation catalysts. Their activity is related to the density of functional groups on the dendrimer periphery, which is a function of the dendrimer generation.…”

This perspective examines the state-of-the-art of catalysis by metal nanoparticles. We outline various methods for preparing metal nanoparticle suspensions, and highlight the role of the stabilizers and the stabilizing principles. Subsequently, we examine some catalytic applications of homometallic and bimetallic nanoparticle suspensions in a variety of reactions. The cases are divided according to the stabilizing agent: polymers, dendrimers, ionic liquids, surfactants, micelles and micoremulsions, ligands and solid supports. We explain the importance of atom/ion leaching (all too frequent in nanoparticle catalysis, especially for the catalytically active group VIII metals) and consider ways of minimizing it. The future perspectives of nanoparticles as catalysts are discussed.

“…Typically, nearly monodispersed nanoparticles in the range of 1-3 nm with a high proportion of accessible metal sites are prepared by this route (90). Whilst the interior of the dendrimer can be tuned to control the metal nanoparticles, the periphery of the dendrimer can also be modifi ed to allow solubility in either organic (91), aqueous (92), supercritical carbon dioxide (93), or fl uorous media (87).…”

Palladium nanoparticles are of great importance as catalytic materials, as well as for a number of other applications such as hydrogen storage and sensing. Their synthesis has been wi dely studied and interest in their properties is growing. Here the synthesis of palladium nanoparticles by chemical and electrochemical methods using a variety of stabilisers including organic ligands, salts/surfactants, polymers and dendrimers is reviewed and their potential benefi ts in catalytic applications are introduced. http://dx.doi.org/10.1595/147106712X632415 •Platinum Metals Rev., 2012, 56, (2)• 84

“…Dendrimer-encapsulated, randomly dispersed metal(0) nanoparticles have been reported [45][46][47][48][49][50][51][52][53][54][55][56] utilizing either the PAMAM or PPI families [57]. The recent report of substrate-specific hydrogenation of olefins with triethoxybenzamide-terminated PPI dendrimers with encapsulated Pd particles demonstrated the unique catalytic internal environment and the potential as dendritic nanoreactors [58].…”
