Research advances of hydrogen storage performance of high-entropy alloys
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.
