Monodisperse single-crystalline sub-10 nm Pt-Pd nanotetrahedrons (NTs) and nanocubes (NCs) were synthesized with high shape selectivity via one-pot hydrothermal routes with small ions as efficient facet-selective agents. These alloy nanocrystals showed facet-dependent enhanced electrocatalytic activity and durability for methanol electrooxidations with commercial Pt/C catalyst as a reference. The (100)-facet-enclosed Pt-Pd NCs demonstrated a higher activity, whereas the (111)-facet-enclosed Pt-Pd NTs exhibited a better durability.
单分散的亚 10nmPt-Pd 纳米四面体（NTs）和纳米立方体（NCs）通过一锅水热法合成，具有高的形状选择性，其中小离子作为高效的面选择性试剂。这些合金纳米晶体表现出与面有关的增强的电催化活性和耐久性，以商业 Pt/C 催化剂作为参考。（100）面封闭的 Pt-Pd NCs 表现出更高的活性，而（111）面封闭的 Pt-Pd NTs 表现出更好的耐久性。
