Abstract:The high-entropy alloys are considered as one of the major breakthroughs in alloying theory in recent decades. They have unique alloy design concept and significant mixing entropy effect, and have potential application prospect in many properties. This paper summarized the research progress of high-entropy alloys catalysts in electrolysis of water in recent years, and introduced the definition and features of high-entropy alloys and the principle of electrolysis of water and catalytic mechanism of high entropy alloys during hydrolysis process, respectively. The research progress is on water hydrogen precipitation and water oxidation in electrolysis of high entropy alloys. The development trend and application prospect of the future of the high-entropy alloys are also prospected.
