摘　　要：高熵合金优异的物理、化学及力学性能,使其在航空、航天、海洋、核能、医疗、新能源等重大领域得到了广泛应用。高熵合金在储氢材料中极具发展潜力,但相关研究目前处于起步阶段,对储氢性能的研究也有限。结合储氢技术对高熵合金材料的需要,综述了目前关于高熵合金储氢性能的研究进展,对近年来国内外高熵合金储氢性能的研究成果进行了总结。研究发现,对高熵合金进行合金化处理可以显著提高储氢容量、改善吸/放氢动力学和循环稳定性等。下一步应深入探究高熵合金的吸/放氢机理,对比研究不同高熵合金储氢性能,并应用于实际的储氢系统进行工程实践。研究成果可为相关领域研究人员提供参考。The excellent physical,chemical and mechanical properties of high-entropy alloys have led to their widespread application in major sectors such as aerospace,marine engineering,nuclear energy,medical and new energy sources.High-entropy alloys show great potential in hydrogen storage materials;however,the related research is still in its infancy,and studies on their hydrogen storage performance are limited.Taking into consideration the needs of hydrogen storage technology for high-entropy alloy materials,this paper summarizes the current research progress on hydrogen storage performance of high-entropy alloys,including recent research results from studies at home and abroad.Research shows that alloying treatment of high-entropy alloys can significantly increase hydrogen storage capacity,improve hydrogen absorption and desorption kinetics,and enhance cycle stability.Future research should focus on further exploring the hydrogen absorption and desorption mechanism of high-entropy alloys,comparing the hydrogen storage performance of different high-entropy alloys,and applying them in engineering practice on actual hydrogen storage system.This study can be used to provide reference for researchers in related fields.
