"A study on the synthesis of Pd-Pt alloy nanoparticles and composition evolution of the alloys was reported. The synthesis followed a hot organometallic route, with Pd and Pt acetylacetonate as the metal precursors and trioctylphosphine as the solvent. The size of the Pd-Pt nanoparticles narrowed down with time and reached a final size of 3.5 nm in about 10 min. The alloy compositions evolved with time and reached the preset Pd to Pt ratio of precursors in 120 min. An atomic exchange process between the Pt-TOP complex and the Pd atoms at the nanoparticle surface was proposed to elucidate this …
