The 1T/2H hybridized and 2H pure phases of MoSnanoflowers were synthesized in a one-step hydrothermal process with the molybdenum source as sodium molybdate dihydrate and the sulfur source as thiourea. The as-prepared 1T/2H hybridized and 2H pure phases of MoSwere investigated using a thermogravimetry\differential thermal analysis, powder x-ray diffraction, field emission scanning electron microscopy, and energy-dispersive x-ray spectroscopy. The obtained 1T/2H hybridized phases of MoSwere confirmed by the Raman spectroscopy. The electrochemical characteristics of MoSelectrodes were examined using cycle voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The electrodes are based on the 1T/2H hybridized phases MoSwith specific capacitance () of 555.4 F gat current densities () of 0.5 A g, capacity retention ratio of 85% after 10 000 cycles were observed that could be a strong potential electrode material for supercapacitors application.
采用水热一步法，以二水合钼酸钠为钼源、硫脲为硫源，合成了MoS纳米花的1T/2H杂化相和2H纯相。使用热重-差热分析、粉末X射线衍射、场发射扫描电子显微镜和能量色散X射线光谱对所制备的MoS的1T/2H杂化相和2H纯相进行了研究。通过拉曼光谱证实了所获得的MoS的1T/2H杂化相。使用循环伏安法、恒电流充放电和电化学阻抗谱对MoS电极的电化学特性进行了研究。这些电极基于1T/2H杂化相的MoS，在电流密度为0.5 A g时比电容为555.4 F g，在10000次循环后容量保持率为85%，有望成为超级电容器应用的强潜在电极材料。
