The shape-controlled synthesis of metal nanocrystals (NCs) has received increasing attention in recent years because NC shape has a profound influence on the optical, magnetic, and catalytic properties of NCs. In particular, the catalytic activities and stabilities of NCs in numerous chemical reactions significantly depend on NC shape. This could be due to specific combinations of the facet types on the NC surface and the overall shape of the NC. In recent years, the synthesis of high-index-faceted NCs has attracted a great deal of attention. High-index facets consist of surface atoms with relatively lower coordination numbers than those of low-index facets due to the presence of high-density atomic steps and kinks on them. Despite the fact that bimetallic NCs have higher catalytic performance than their monometallic counterparts and that their properties can be tuned by tailoring their morphologies, the synthesis of high-index-faceted bimetallic NCs has been relatively unexplored compared to monometallic NCs. Herein, the synthesis of high-index-faceted bi-metallic NCs with unprecedented morphologies and their unique catalytic properties are reported.
