Traditional material design concept has limited the development of higher performance catalysts.As a type of multi-element material,the high-entropy alloy(HEA),renovates the traditional alloy concept and exhibits excellent catalytic activity due to the high configuration entropy and catalytic stability.The nanoparticles(NPs)like Ru-NPs,Pt-NPs with a diameter of less than 10 nm have a better catalytic effect than large-size catalysts.Recently,the synergistic catalytic effect of HEA and NPs has been of great interest to researchers,creating a kind of new catalytic materials,namely HEA-NPs composites[1-2].
