Nanosized particles of pure palladium were produced by pulsed laser ablation in aqueous solution, with and without the addition of sodium dodecyl sulfate as the surfactant agent. The work was motivated by the strong catalytic effect of Pd particles in many chemical reactions. The influence of experimental parameters, such as laser energy and beam focusing as well as surfactant concentration, on the laser ablation process, nanoparticle mass yield, and nanoparticle properties was investigated via plasma imaging, UV−visible spectroscopy, transmission electron microscopy/energy dispersive spectroscopy (TEM-EDS) analysis, and measurement of ζ potential. The surface-enhanced Raman scattering activity of nanoparticles was used for the monitoring of their adsorption capability on the metal surface during catalysis processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
