以钼酸（H₂MoO₄）和硫氰酸铵（NH₄SCN）为原料，将导电玻璃垂直悬挂在水热反应釜中，采用水热法在220℃的条件下，成功原位制备出二硫化钼薄膜，并考察了不同反应时间（12、24、36 h）对水热法制备二硫化钼的影响。利用X射线衍射（XRD）、扫描电子显微镜（SEM）、X射线光电子能谱（XPS）对所制备的二硫化钼的物相、形貌和成分进行了表征。利用电化学工作站对二硫化钼薄膜电极进行光电化学、阻抗谱和Mott-Schottky曲线的测试，结果表明，水热反应24 h制备的样品具有更优异的光电化学性能。

Molybdenum disulfide film electrodes are in situ manufactured by hydrothermal method with molybdic acid and ammonium thiocyanate as raw materials and conductive glass hanging in the Teflon-sealed autoclave.The effect of hydrothermal time (12,24 and 36 h) on the properties of MoS₂ is investigated.The as-prepared samples are characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).The photoelectrochemisty,electrochemical impedance spectra (EIS) and Mott-Schottky curve of MoS₂ thin film electrodes are tested on an electrochemical workstation,which indicates that MoS₂ sample prepared in 24 h of hydrothermal time possesses better photoelectrochemical performance.
