In recent years, intermetallic nanocrystals (IMNCs) have attracted extensive attention in the field of electrocatalysis. However, precise control over the size, shape, composition, structure, and exposed crystal facet of IMNCs seems to be a challenge to the traditional method of high-temperature annealing although these parameters have a significant effect on the electrocatalytic performance. Controllable synthesis of IMNCs by the wet chemistry method in the liquid phase shows great potential compared with the traditional high-temperature annealing method. In this Review, we attempt to summarize the preparation of IMNCs by the seed-mediated synthesis in the liquid phase, as well as their applications in electrocatalytic reduction reactions. Several representative examples are purposely selected for highlighting the huge potential of the seed-mediated synthesis approach in chemical synthesis. Specifically, we personally perceive the seed-mediated synthesis approach as a promising tool in the future for precise control over the size, shape, composition, structure, and exposed crystal facet of IMNCs.
近年来，金属间化合物纳米晶体（IMNCs）在电催化领域引起了广泛关注。然而，尽管这些参数对电催化性能有显著影响，但对IMNCs的尺寸、形状、组成、结构和暴露晶面进行精确控制似乎对传统的高温退火方法来说是一项挑战。与传统的高温退火方法相比，通过湿化学方法在液相中可控合成IMNCs显示出巨大潜力。在这篇综述中，我们试图总结通过液相种子介导合成法制备IMNCs及其在电催化还原反应中的应用。特意选择了几个代表性例子以突出种子介导合成方法在化学合成中的巨大潜力。具体而言，我们个人认为种子介导合成方法是未来精确控制IMNCs尺寸、形状、组成、结构和暴露晶面的一种有前景的工具。
