A type of rock candy-shaped Mn3O4 nanoparticles was synthesized by a facile hydrothermal approach with Pluronic P123 and polyethylene glycol (PEG200), which were chosen as template and reducing agent, respectively. The co-surfactant system played a crucial role in the growth of nanoparticles. In addition, Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) were employed to confirm the morphology and structure. These results demonstrated that the length-width ratios of the as-prepared Mn3O4 nanoparticles were about 1.0-1.4 and the average size was about 200 nm. Furthermore, the product presented high-stability electrochemical performances both in the 1.0 M Na2SO4 and in 1.0 M KOH electrolytes, which had the potential as an electrode material for energy conversion and storage devices.
采用简便的水热法，分别以普朗尼克P123和聚乙二醇（PEG200）作为模板和还原剂，合成了一种冰糖状的Mn3O4纳米颗粒。共表面活性剂体系在纳米颗粒的生长过程中起着关键作用。此外，采用透射电子显微镜（TEM）和X射线衍射（XRD）来确认其形态和结构。这些结果表明，所制备的Mn3O4纳米颗粒的长宽比约为1.0 - 1.4，平均尺寸约为200 nm。此外，该产物在1.0 M Na2SO4和1.0 M KOH电解质中均表现出高稳定性的电化学性能，具有作为能量转换和存储装置电极材料的潜力。
