Abstract

The TEM micrographs for the polymerized and thiolized palladium nanoparticle showed a well-dispersed particle with a mean particle diameter of 4.5 nm and 2.5 nm for [Pd-PVP] and [Pd-C12SH] nanoparticles respectively. The bimetallic [Pd0.9Ni0.1] nanocluster has a particle average diameter size of 2.75 nm for the PVP-polymerized nanocluster but has a very narrow mean particle size of 2.1 nm for the thiolized form. The notably very narrow range of particle size, uniformly dispersed particle structure of the thiolized nanocluster, and the absence of evidence of the bimodal forms in the particle structure suggest strongly an "alloying" structure of the Pd and Ni particles. This "alloying" effect will have to be further investigated using high-energy spectroscopy to affirm the said effect.
