Amorphous molybdenum selenide nanopowder, obtained by refluxing Mo(CO)₆ and Se precursors in dichlorobenzene, shows several structural and electrochemical similarities to the amorphous molybdenum sulfide analogue. The molybdenum selenide displays attractive catalytic properties for the hydrogen evolution reaction in water over a wide range of pH. In a pH 0 solution, it operates with a small onset overpotential of 125 mV and requires an overpotential of 270 mV for generating a catalytic current of 10 mA/cm². Compared with molybdenum sulfide, the selenide analogue is more robust in a basic electrolyte. Therefore, molybdenum selenide is a potential candidate for incorporating within an electrolyzer or a photoelectrochemical cell for water electrolysis in acidic, neutral, or alkaline medium.

新型非晶态硒化钼作为高效的产氢反应催化剂

通过在二氯苯中回流Mo（CO）₆和Se前驱体获得的非晶态硒化钼纳米粉，与非晶态硫化钼类似物具有若干结构和电化学相似性。硒化钼在很宽的pH值范围内，对于水中的氢气析出反应显示出诱人的催化性能。在pH 0的溶液中，它的起始超电势很小，只有125 mV，并且需要270 mV的超电势才能产生10 mA / cm ²的催化电流。。与硫化钼相比，硒化物类似物在碱性电解液中更坚固。因此，硒化钼是用于在酸性，中性或碱性介质中进行水电解的电解槽或光电化学槽内的潜在候选物。
