Alloy allies: Trisoctahedral (TOH) Au–Pd alloy nanocrystals (NCs; see figure) 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.
