Because H2 is considered a promising clean energy source, water electrolysis has attracted great interest in related research and technology. Noble‐metal‐based catalysts are used as electrode materials in water electrolyzers, but their high cost and low abundance have impeded them from being used in practical areas. Recently, metal sulfides and phosphides based on earth‐abundant transition metals have emerged as promising candidates for efficient water‐splitting catalysts. Most studies have focused on adjusting the composition of the metal sulfides and phosphides to enhance the catalytic performance. However, morphology control of catalysts, including faceted and hollow structures, is much less explored for these systems because of difficulties in the synthesis, which requires a deep understanding of the nanocrystal growth process. Herein, representative synthetic methods for morphology‐controlled metal sulfides and phosphides are introduced to provide insights into these methodologies. The electrolytic performance of morphology‐controlled metal sulfide‐ and phosphide‐based nanocatalysts with enhanced surface area and intrinsically high catalytic activity is also summarized and the future research directions for this promising catalyst group is discussed.

形态控制的金属硫化物和磷酸盐用于电化学水分解
因为H 2水电解被认为是一种有前途的清洁能源，引起了相关研究和技术的极大兴趣。贵金属基催化剂在水电解槽中用作电极材料，但是它们的高成本和低丰度阻碍了它们在实际领域中的使用。最近，基于富含地球的过渡金属的金属硫化物和磷化物已成为有效的水分解催化剂的有前途的候选者。大多数研究集中在调节金属硫化物和磷化物的组成以增强催化性能上。然而，由于合成困难，对于这些体系，包括多面和空心结构的催化剂的形态控制很少探索，这需要对纳米晶体的生长过程有深入的了解。在此处，介绍了用于形态学控制的金属硫化物和磷化物的代表性合成方法，以深入了解这些方法。还总结了形态可控的金属硫化物和磷化物基纳米催化剂的电解性能，这些催化剂具有增加的表面积和本质上高的催化活性，并讨论了该有前途的催化剂组的未来研究方向。
