A perspective on high‐entropy two‐dimensional materials

In past decades, high-entropy (HE) materials, containing five or more elements with approximately equal atomic ratio, are extensively investigated due to their desirable properties in a series of applications. Recently, HE two-dimensional (2D) materials have become promising which not only endow the advantages from bulk form but also exhibit unusual 2D features. So far, transition metal carbides (MXenes), dichalcogenides (TMDs), hydrotalcites (LDHs), and oxides been successfully synthesized performed well different electrochemical reactions, is originated synergistic effect multicomponents thin characteristics. Here, challenges on processing, characterization, property predictions emphasized. Finally, viable strategies, advanced fundamental understanding, in-depth characterization new proposed.
