Decoding the Hume–Rothery Rule in a Bifunctional Tetra-metallic Alloy for Alkaline Water Electrolysis The 90-year-old Hume–Rothery rule was adapted to design an outstanding bifunctional tetra-metallic alloy electrocatalyst for water electrolysis. Following the radius mismatch principles, Fe (131 pm) a...

In Nano Letters, we showcase how the 90-year-old Hume-Rothery rule (Z. Kristallogr. Cryst. Mater. 1935, 91, 23-47) guides the design of a cutting-edge bifunctional tetra-metallic catalyst for water electrolysis
