Journal ArticleDOI
Ligand-stabilized ruthenium nanoparticles: synthesis, organization, and dynamics.
Cheng Pan,Katrin Pelzer,Karine Philippot,Bruno Chaudret,Fabrice Dassenoy,Pierre Lecante,Marie-José Casanove +6 more
TL;DR: A catalytic transformation of thiols into disulfides has been observed which involves oxidative addition ofThiols on the ruthenium surface which leads to agglomerated particles or particles dispersed in the solution, both displaying a mean size near 2--3 nm and an hcp structure.
Journal ArticleDOI
A case for enantioselective allylic alkylation catalyzed by palladium nanoparticles.
Susanna Jansat,Montserrat Gómez,Karine Philippot,Guillermo Muller,Ester Guiu,Carmen Claver,Sergio Castillón,Bruno Chaudret +7 more
TL;DR: This is the first colloidal system shown to display such a high enantioselectivity besides the well-known Pt/cinchonidine system.
Journal ArticleDOI
Influence of organic ligands on the stabilization of palladium nanoparticles
Esther Ramirez,Susanna Jansat,Karine Philippot,Pierre Lecante,Montserrat Gómez,Anna M. Masdeu-Bultó,Bruno Chaudret +6 more
TL;DR: In this article, it was shown that good ligands lead to stable spherical nanoparticles of small size (near 2 nm) whereas the protective effect of HDA depends on the amount of ligand added as a result of equilibria present at the surface of the particles as monitored by solution NMR spectroscopy.
Journal ArticleDOI
Organometallic approach to the synthesis and surface reactivity of noble metal nanoparticles
Karine Philippot,Bruno Chaudret +1 more
TL;DR: The use of organometallic precursors allows the synthesis in mild conditions of nanoparticles of uniform small size and of clean surface, which can be stabilized by polymers or ligands.
Journal ArticleDOI
Organometallic Synthesis of Size‐Controlled Polycrystalline Ruthenium Nanoparticles in the Presence of Alcohols
TL;DR: In this article, Ru nanoparticles of controlled size have been prepared by decomposition of the organometallic precursor Ru(cod)(cot) under an H2 atmosphere in either a pure alcohol or an alcohol/THF mixture as solvent and in the absence of further stabilizer.
