Abstract

Herein, we report the synthesis of metallic molybdenum microspheres and hierarchical MoS nanostructures by facile template-free solvothermal and hydrothermal approach, respectively. The morphological transition of the Mo microspheres to hierarchical MoS nanoflower architectures is observed to be accomplished with change in solvent from ethylenediamine to water. The resultant marigold flower-like MoS nanostructures are few layers thick with poor crystallinity while spherical ball-like molybdenum microspheres exhibit better crystalline nature. This is the first report pertaining to the synthesis of Mo microspheres and MoS nanoflowers without using any surfactant, template or substrate in hydro/solvothermal regime. It is opined that such nanoarchitectures of MoS are useful candidates for energy related applications such as hydrogen evolution reaction, Li ion battery and pseudocapacitors. Inquisitively, metallic Mo can potentially act as catalyst as well as fairly economical Surface Enhanced Raman Spectroscopy (SERS) substrate in biosensor applications.

摘要

在此，我们分别通过简便的无模板溶剂热法和水热法报道了金属钼微球和分级MoS纳米结构的合成。观察到Mo微球向分级MoS纳米花结构的形态转变是通过将溶剂从乙二胺变为水来实现的。所得的金盏花状MoS纳米结构为几层厚，结晶性较差，而球形钼微球表现出更好的结晶性质。这是关于在水热/溶剂热体系中不使用任何表面活性剂、模板或基底合成Mo微球和MoS纳米花的首次报道。据认为，这种MoS纳米结构是用于诸如析氢反应、锂离子电池和赝电容器等与能源相关应用的有用候选材料。有趣的是，金属Mo在生物传感器应用中可能既充当催化剂又充当相当经济的表面增强拉曼光谱（SERS）基底。
