High-entropy materials, a new class of alloys that incorporate five or more principal elements into single-phase crystal structures, have received considerable interest in materials science and engineering. Considering the tailored composition and disordered configuration, these high-entropy materials may arouse functional synergism towards electrocatalysis. Here, a new strategy for preparing high-entropy metal phosphides (HEMPs) was developed by a eutectic solvent method. The as-prepared HEMP possessed a single metal phosphide phase with up to five homogenously distributed metal components. The versatile application of high-entropy materials was highlighted by integrating the HEMP catalyst into a two-electrode configuration for electrocatalytic water splitting.

用于电催化水分解的高熵金属磷化物的共晶合成。

高熵材料是一种将五种或更多种主要元素结合到单相晶体结构中的新型合金，在材料科学和工程领域引起了极大的兴趣。考虑到量身定制的组成和无序的构型，这些高熵材料可能会激发电催化的功能协同作用。在这里，通过共晶溶剂法开发了一种制备高熵金属磷化物（HEMPs）的新策略。所制备的HEMP具有单一的金属磷化物相，具有多达五个均匀分布的金属成分。通过将HEMP催化剂集成到用于电催化水分解的两电极配置中，突出了高熵材料的广泛应用。
