Abstract

Altering the physical and chemical properties of a layered material through intercalation has emerged as a unique strategy toward tunable applications. In this work, we demonstrate a wet chemical method to intercalate titanium, hafnium, and zirconium into 2D layered nanomaterials. The metals are intercalated using bis-tetrahydrofuran metal halide complexes. Metal intercalation is demonstrated in nanomaterials of Bi₂Se₃, Si₂Te₃, MoO₃, and GeS. This strategy intercalates, on average, 3 atm % or less of Hf, Ti, and Zr that share charge with the host nanomaterial. This methodology is used to chemochromically alter MoO₃ from transparent white to dark blue.

二维层状纳米材料中的铪、钛和锆互嵌

通过插层改变层状材料的物理和化学特性已成为实现可调应用的一种独特策略。在这项研究中，我们展示了一种将钛、铪和锆插层到二维层状纳米材料中的湿化学方法。这些金属是利用双四氢呋喃金属卤化物络合物插层的。金属插层在 Bi2Se3、Si2Te3、MoO3 和 GeS 纳米材料中得到了验证。这种策略平均可插层 3 atm % 或更少的 Hf、Ti 和 Zr，它们与主纳米材料共享电荷。这种方法可将 MoO3 从透明的白色变成深蓝色。
