高熵材料是一类由多种元素以等摩尔比或者近等摩尔比组成的新型多主元材料,包括高熵合金和一系列高熵化合物,如高熵氧化物和氢氧化物、高熵磷化物、高熵硫化物、高熵甘氨酸盐等。高熵材料具备无序的组成成分、广泛的可调控性和特殊的物理化学性质,具有成为高效析氧催化剂的潜力,有望成为一种新型的电解水析氧反应催化剂,能够取代传统金属氧化物和标准贵金属基催化剂用于催化电解水析氧反应。本文主要对近年来高熵材料在析氧反应催化剂方面的研究进展进行了总结,对高熵材料未来在电解水制氢领域的发展趋势和应用前景进行了展望。

High entropy materials are a new kind of multi-principal component materials composed of many elements in equal or near equal molar ratio, including high entropy alloys and a series of high entropy compounds, such as high entropy oxides and hydroxides, high entropy phosphates, high entropy sulfides, high entropy glycine salts, etc. High entropy materials have disordered components, wide adjustability, and spe-cial physical and chemical properties. They have the potential to become high-efficiency oxygen evolution catalysts, and may become a new type of electrolytic water oxygen evolution reaction cat-alyst, which can replace the traditional metal oxides and standard noble metal-based catalysts for catalytic electrolytic water oxygen evolution reaction. In this paper, the research progress of high entropy materials in oxygen evolution reaction catalysts in recent years is summarized, and the development trend and application prospect of high entropy materials in hydrogen production from electrolytic water in the future are prospected.
