随着世界性的能源危机，人类希望寻找一种新型能源来替代化石能源，氢气具有高燃烧热值，可用以储能。各国学者寄希望于能够通过电解水来生产氢气，以缓解能源危机。但析氢反应的热力学过电位较大，降低了能量转换效率，因而在反应时需利用催化剂来降低过电位以提高转换效率。目前使用的催化剂中，铂的性能最好，但铂是稀有金属，而且其在酸性条件下是受限制的，这限制了铂在工业领域的广泛使用。近些年来，具有独特电子和光学特性的硫化钼被发现是一种可利用的HER催化剂，特别是在酸性条件下具有较高稳定性，但其催化性能因稀疏的催化边缘位点和不良的导电性而受到限制。所以，对硫化钼HER催化剂的进一步研究的首要问题是如何在外表面暴露更多的催化活性位点，并提高其稳定性，同时致力于找寻更廉价的原料。本论文在前人的基础上，通过水热法，添加表面活性剂以在基底（碳纸、泡沫镍）上结晶生长纳米级的二硫化钼，通过一系列对照实验，发现以泡沫镍为基底、添加0.5 mmol CTAB和10 mmol硫脲制得的复合催化性能最优，在电流密度为10 mA/cm2时所需过电位为97 mV，且在电流密度较大时仍具有较低的过电位。证明了合成的材料具有良好的电化学析氢效果。

With the global energy crisis, humanity hopes to find a new energy source to replace fossil energy. Hydrogen has a high combustion calorific value and can be used for energy storage. Scholars from all over the world hope that they can produce hydrogen by electrolyzing water to ease the energy crisis. However, the thermodynamic over potential of the hydrogen evolution reaction is large, which reduces the energy conversion efficiency. Therefore, it is necessary to use a catalyst to reduce the over potential in the reaction to increase the conversion efficiency. Among the currently used catalysts, platinum has the best performance, but platinum is a rare metal, and it is limited under acidic conditions, which limits the widespread use of platinum in the industrial field. In recent years, molybdenum sulfide with unique electronic and optical properties has been found to be an available HER catalyst, especially with high stability under acidic conditions, but its catalytic properties are due to sparse catalytic edge sites and poor Conductivity is limited. Therefore, the first question for the further study of the molybdenum sulfide molybdenum catalyst is how to expose more catalytically active sites on the outer surface and increase its stability while seeking to find cheaper raw materials. On the basis of the predecessors, this paper adopted hydrothermal method to add surfactants to crystallize Nano-sized molybdenum disulfide on the substrate (carbon paper, nickel foam). Through a series of comparative experiments, it was found that the nickel foam was used as the base. The optimum catalytic performance was obtained by adding 0.5 mmol CTAB and 10 mmol thiourea. The required over potential is 97 mV at the current density of 10 mA/cm2, and the over-potential is still low when the current density is high. . It is proved that the synthesized material has a good electrochemical hydrogen evolution effect.
