Preparing water-dispersed palladium nanoparticles via polyelectrolyte nanoreactors

Abstract

A counterion-induced polyelectrolyte collapse strategy has been developed for the preparation of poly(acrylic acid) stabilized palladium nanoparticles (NP-Pd-PAA). The structure and composition of the nanoparticles were investigated via transmission electron microscopy, dynamic light scattering, powder X-ray diffraction, and X-ray photoelectron spectroscopy. NP-Pd-PAA catalyzed fully aqueous Suzuki coupling reactions at loadings as low as 0.01 mol% Pd.
