我们已经开发了一种化学方法来插入各种零价金属原子到二维（2D）层状Bi2Se3硫属化物纳米带。我们使用化学反应，如反离子化氧化还原反应，以产生稀释的零价金属原子在一个无水溶液中，插入到层状Bi2Se3结构。嵌入剂的零价性质允许金属原子如Ag、Au、Co、Cu、Fe、In、Ni和Sn的超化学计量嵌入。我们预见这种方法在建立新的基本物理行为和可能的能源应用的影响。
We have developed a chemical method to intercalate a variety of zerovalent metal atoms into two-dimensional (2D) layered Bi2Se3 chalcogenide nanoribbons. We use a chemical reaction, such as a disproportionation redox reaction, to generate dilute zerovalent metal atoms in a refluxing solution, which intercalate into the layered Bi2Se3 structure. The zerovalent nature of the intercalant allows superstoichiometric intercalation of metal atoms such as Ag, Au, Co, Cu, Fe, In, Ni, and Sn. We foresee the impact of this methodology in establishing novel fundamental physical behaviors and in possible energy applications.
