Amorphous‐Crystalline Interfaces on Hollow Nanocubes Derived from Ir‐Doped Ni–Fe–Zn Prussian Blue Analog Enables High Capability of Alkaline/Acidic/Saline Water Oxidations

catalyst, regardless of chemical environment of electrolytes. Hence, this work can be an instructive guidance for developing the ACI engineered electroctalyst which can be diversely used for different types of low-temperature electrolyzers.
