Bimetallic Pt-based nanodendrites are of particular interest in various catalytic applications due to their high surface areas and low densities. Herein, we provide a facile method for one-pot synthesis of PtRu nanodendrites via the co-reduction of Pt and Ru precursors in oleylamine by H. The as-fabricated PtRu nanodendrites exhibit superior catalytic activity and durability compared with PtRu nanocrystals (NCs), synthesized under the same reaction conditions, and the commercial Pt/C catalyst towards the methanol oxidation reaction (MOR).
双金属 Pt 基纳米枝晶因其具有高比表面积和低密度而在各种催化应用中受到特别关注。在此，我们提供了一种简便的一锅法，通过 H 在油胺中还原 Pt 和 Ru 前体制备 PtRu 纳米枝晶。与在相同反应条件下合成的 PtRu 纳米晶（NCs）和商业 Pt/C 催化剂相比，所制备的 PtRu 纳米枝晶对甲醇氧化反应（MOR）表现出更高的催化活性和耐久性。
