Abstract:
Alloy allies: trisoctahedral (TOH) Au-Pd alloy nanocrystals (NCs) enclosed exclusively by {441} high-index facets have been synthesized. Precise control over the reductant/surfactant concentration and the molar ratio of metal precursors allowed the optimization of growth kinetics of the NCs, which is the key to the successful formation of TOH Au-Pd NCs. The prepared NCs exhibited excellent catalytic performance towards the Suzuki coupling reaction due to their alloyed surfaces with high-index facets.
