Pd-PVP colloid as catalyst for Heck and carbonylation reactions: TEM and XPS studies

Rh(0) Nanoparticles: Synthesis, Structure and Catalytic Application in Suzuki–Miyaura Reaction and Hydrogenation of Benzene

“…The observation that stronger reducing agents lead to small nanoparticles in a rapid reaction, whereas weaker reducing agents produce larger particles is in agreement with our earlier studies of PVP-protected Pd(0) colloids [34,35]. The growth of the larger polycrystalline particles, in case of application of 2-butanol as the reducing agent, might be also explained from the thermodynamical point of view.…”

Recent Advances in the Liquid‐Phase Synthesis of Metal Nanostructures with Controlled Shape and Size for Catalysis

“…Ex situ prepared stabilized colloidal Pd (6,(134)(135)(136)(137) and Ru (138) nanoparticles have gained considerable attention due to their high activity and recyclability. Pd equidimensional nanoparticles of mean sizes from 1.7 to 3.7 nm stabilized by PVP were used as a catalytic probe to study structure sensitivity of Heck coupling of p-bromobenzaldehyde with butyl acrylate (25).…”

Effect of size and oxidation state of size-controlled rhodium nanoparticles on the aqueous-phase hydrodechlorination of 4-chlorophenol

“…Thus, the studies on the preparation and application in nanosized catalysts have increased significantly [21]. Different methods of synthesis addressed to obtain size-controlled nanoparticles have been reported [22][23][24]. Among them, chemical reduction has been frequently used due to its simple mechanism consisting on the reduction of a metal salt with a reducing agent (e.g.…”
