Ultrathin and ultralong: Highly uniform, ultrathin (diameter 5-7 nm), and ultralong (aspect ratio >10(4)) PtPdTe nanowires (NWs) were synthesized by using a facile method employing Te NWs as both sacrificial templates and reducing agents. Fine-tuning of the molar ratios of Pt and Pd precursors afforded PtPdTe NWs with different compositions and enhanced electroactivity in the methanol oxidation reaction in comparison with a commercial Pt/C catalyst.
超薄和超长
通过使用一种简便的方法，使用 Te NWs 作为牺牲模板和还原剂，合成了高度均匀的超薄（直径 5-7nm）和超长（纵横比>10(4)）PtPdTe 纳米线（NWs）。通过精细调节 Pt 和 Pd 前体的摩尔比，可以得到具有不同组成的 PtPdTe NWs，与商业 Pt/C 催化剂相比，在甲醇氧化反应中具有增强的电活性。
