|Title:||Au nanoparticles encapsulated in Ru carbonyl carboxylate shells||Authors:||Wang, S.
|Issue Date:||29-Aug-2006||Citation:||Wang, S., Sim, W.-S. (2006-08-29). Au nanoparticles encapsulated in Ru carbonyl carboxylate shells. Langmuir 22 (18) : 7861-7866. ScholarBank@NUS Repository. https://doi.org/10.1021/la060784f||Abstract:||A two-step surface functionalization approach has been used to encase Au nanoparticles in monolayer organometallic Ru-complex shells by the reaction of an intermediate surface-bound mercaptopropanoic acid capping species with Ru dodecacarbonyl (Ru3(CO)12) clusters. Vibrational (infrared and Raman) spectroscopy shows that insertion of carboxylate groups into the Ru clusters results in their fragmentation and the formation of a shell of Ru dicarbonyl carboxylate oligomers that remain attached to the Au nanoparticles through the original Au-alkanethiolate bonds. The structural integrity of the metallic nanoparticulate Au cores has been verified by X-ray photoelectron spectroscopy, X-ray diffraction, and transmission electron microscopy. The organometallic Ru-complex shell may be decomposed thermally to eliminate the mercaptopropanoate and carbonyl groups and leave a mixed phase of Au and RuO2. © 2006 American Chemical Society.||Source Title:||Langmuir||URI:||http://scholarbank.nus.edu.sg/handle/10635/93156||ISSN:||07437463||DOI:||10.1021/la060784f|
