The design of porous bimetallic nanocrystals (NCs) is very important for electrochemical energy conversion. Herein, we report an aqueous solution method for one-step fabrication of porous PtCu NCs assembled by spatially interconnected arms in high yield by a simple ultrasonic treatment of the reaction mixture at room temperature. The proposed method, without the need for multi-step synthesis, high temperatures, and organic solvents, shows an obvious advantage of simplicity for the feasible synthesis of bimetallic PtCu NCs with a porous structure. The as-made porous PtCu NCs are highly active and durable catalysts for the methanol oxidation reaction due to their porous structure and bimetallic composition.
多孔双金属纳米晶体 (NCs) 的设计对于电化学能量转换非常重要。在此，我们报告了一种在室温下通过简单的超声处理反应混合物一步制备多孔 PtCu NCs 的水溶液方法，该方法产率高，由空间相互连接的臂组装而成。所提出的方法无需多步合成、高温和有机溶剂，具有明显的优势，可通过简单的方法来合成具有多孔结构的双金属 PtCu NCs。所制备的多孔 PtCu NCs 由于其多孔结构和双金属组成，是甲醇氧化反应的高活性和耐用催化剂。
