Water Splitting: A Novel Multinary Intermetallic as an Active Electrocatalyst for Hydrogen Evolution (Adv. Mater. 21/2020)

In article number 2000385, Jian Lu, Chain Tsuan Liu, and co‐workers develop a novel multinary high‐entropy intermetallic (HEI) with an unusual periodically ordered structure and multiple low‐cost elements that present superior water‐splitting performance in both efficiency and stability when compared to the current state‐of‐the‐art systems. The excellent performance for water splitting is mainly due to the chemical complexity, the unique site‐isolation effect, and the dendrite‐like porous morphology.
