This invention relates to a hollow molybdenum diselenide microsphere and its preparation method. The product is prepared by the following steps: ammonium molybdate is weighed and dissolved in deionized water, stirred until completely dissolved; dopamine hydrochloride is then added to the resulting solution and stirred until homogeneous; anhydrous ethanol is added to the resulting solution and stirred until homogeneous; ammonia is added dropwise to the resulting solution; the resulting solution is allowed to stand at room temperature for a period of time, washed, and dried to obtain a precursor; the obtained precursor and selenium powder are placed in an inert atmosphere and calcined in a sealed environment, then naturally cooled to room temperature to obtain the hollow molybdenum diselenide microsphere. The beneficial effects of this invention are: it can suppress the shuttle effect of polysulfides through strong electronic interactions with polysulfides, promoting the catalytic conversion process of polysulfides, making it an ideal high-efficiency electrocatalyst; simultaneously, the hollow structure can physically confine polysulfides, thereby effectively suppressing the shuttle effect of polysulfides.
