Abstract:	Rhenium (Re) nanoparticles have been synthesized by pulsed-laser decomposition of ammonium perrhenate (NH 4ReO 4) or dirhenium decacarbonyl (Re 2(CO) 10) in the presence of 3-mercaptopropionic acid (MPA) as capping agent, in both aqueous and organic media. Preliminary studies showed that the MPA-capped Re nanoparticles are capable of catalyzing the isomerization of 10-undecen-1-ol to internal alkenols via long chain migration of the CC double bond at ca. 200°C. A one-pot synthesis of graphite-coated Re nanoparticles has also been achieved by pulsed-laser decomposition of Re 2(CO) 10, due to photo-induced catalytic graphitization of the phenyl groups of PPh 3 on the surface of rhenium nanoparticles. © 2011 Elsevier Inc.
