Abstract

The synthesis of high-entropy metal chalcogenides has long been constrained by the constraints of high-temperature synthesis, a process that is both time-intensive and energy-demanding due to formidable entropic barriers. Herein, we report a rapid, cost-effective, and ambient-temperature synthesis of high-entropy metal chalcogenides entirely in aqueous solution. This mild yet potent approach facilitates the formation of (NiCoFeMnCr)S, (NiCoFeMnCr)Se and (NiCoFeMnCr)Te which exhibit outstanding performance for the oxygen evolution reaction. Remarkably, this method is readily scalable, capable of producing over 100 g of high-entropy sulfide materials in a single batch. Beyond delivering highly active and energy-efficient OER electrocatalysts, this work establishes a versatile and sustainable pathway for the low-temperature, large-scale synthesis of diverse high-entropy nanomaterials, broadening the synthetic landscape for next-generation energy technologies.

高熵硫族化合物在环境和可扩展合成中的高效OER催化

高熵金属硫族化合物的合成长期以来受到高温合成的限制，由于巨大的熵垒，这一过程既耗时又耗能。在此，我们报告了一种在水溶液中快速、经济、室温合成高熵金属硫族化合物的方法。这种温和而有效的方法促进了（NiCoFeMnCr）S, (NiCoFeMnCr)Se和（NiCoFeMnCr）Te的形成，在析氧反应中表现出优异的性能。值得注意的是，这种方法易于扩展，能够在单批中生产超过100 g的高熵硫化物材料。除了提供高活性和节能的OER电催化剂外，这项工作还为低温、大规模合成各种高熵纳米材料建立了一条通用的、可持续的途径，拓宽了下一代能源技术的合成领域。
