Abstract This work presents an epitaxial deposition of a thin film of single crystal MoTe2 nanorods via electrodeposition at room temperature from aqueous based electrolyte purged with argon. The method allows control over film morphology through deposition potential. In a typical deposition performed at −0.8 V vs Ag/AgCl for 10 min, film comprised of 1D MoTe2 nanorods is obtained, while the deposition at −0.9 V vs Ag/AgCl renders nanoplate like structure. When characterized with FE-SEM, XRD, TEM, SAED and Raman spectroscopy, the film shows uniform deposition of single crystal MoTe2 nanorods particularly with metallic 1 T’ phase. In a preliminary test on feasibility of the nanorod film as anode material for Li-ion storage, a promising result is perceived showing discharge capacity of about 770 mAhg−1 with good electrochemical reversibility.

单晶 MoTe2 纳米棒的外延电沉积和 Li+ 存储可行性

摘要 这项工作介绍了在室温下通过用氩气吹扫的水基电解质电沉积单晶 MoTe2 纳米棒薄膜的外延沉积。该方法允许通过沉积电位控制膜形态。在 -0.8 V vs Ag/AgCl 下进行的典型沉积 10 分钟，获得了由 1D MoTe2 纳米棒组成的薄膜，而在 -0.9 V vs Ag/AgCl 下的沉积呈现纳米片状结构。当用 FE-SEM、XRD、TEM、SAED 和拉曼光谱表征时，该薄膜显示出单晶 MoTe2 纳米棒的均匀沉积，特别是具有金属 1T' 相。在对纳米棒薄膜作为锂离子存储负极材料可行性的初步测试中，发现了一个有希望的结果，显示出约 770 mAhg-1 的放电容量和良好的电化学可逆性。
