Nanoscale palladium is commonly used as a catalyst and holds promise for many other applications. Environmental exposure to nanoscale palladium could have profound effects due to its reactivity. We investigated the stability of palladium nanoparticles (PdNPs) under simulated oxidative environmental conditions. We synthesized PdNPs via a modified aqueous reduction procedure and examined their stability using an in vitro biomimetic oxidative assay. Palladium nanoparticle transformation was characterized using a variety of analytical methods. Our results will be presented.
