在此，我们分别报道了通过简便的无模板溶剂热法和水热法合成金属钼微球和分级MoS2纳米结构。观察到Mo微球向分层MoS2纳米花结构的形态转变是通过将溶剂从乙二胺变为水来完成的。所得的万寿菊花状MoS2纳米结构层数少，结晶度较差，而球状钼微球则表现出更好的结晶性质。这是第一篇关于在水/溶剂热体系中不使用任何表面活性剂、模板或底物合成 Mo 微球和 MoS2 纳米花的报告。人们认为，MoS2 的这种纳米结构对于氢析出反应、锂离子电池和赝电容器等能源相关应用来说是有用的候选者。令人好奇的是，金属钼可以在生物传感器应用中充当催化剂以及相当经济的表面增强拉曼光谱（SERS）基底。
Herein, we report the synthesis of metallic molybdenum microspheres and hierarchical MoS2 nanostructures by facile template-free solvothermal and hydrothermal approach, respectively. The morphological transition of the Mo microspheres to hierarchical MoS2 nanoflower architectures is observed to be accomplished with change in solvent from ethylenediamine to water. The resultant marigold flower-like MoS2 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 MoS2 nanoflowers without using any surfactant, template or substrate in hydro/solvothermal regime. It is opined that such nanoarchitectures of MoS2 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.
