These results demonstrate the extensibility of the corrosion engineering method.
In addition, this corrosion engineering method is scaled up easily.
In summary, a corrosion engineering method has been presented for the value-added transformation of inexpensive iron substrates into high-performance electrodes for OER.
The above comparisons suggest, the corrosion engineering method is a simple, yet scalable and cost-effective, way to access this class of materials with multiple functions.
Here we develop an energy-efficient, cost-effective, scaled-up corrosion engineering method for transforming inexpensive iron substrates (e.g., iron plate and iron foam) into highly active and ultrastable electrodes for oxygen evolution reaction.
Next, the electrocatalytic property for OER of the material from the corrosion engineering method (labeled as Route 1) in the aqueous solution containing Ni2+ cations are investigated in a detailed way.
This claim is further supported by the activity comparison of a series of electrodes fabricated by our corrosion engineering method in the corrosive environments containing different Ni2+ concentrations (Supplementary Fig. 14).
The above results overall demonstrate the meliority of our corrosion engineering method over the electrochemical deposition method and other methods reported recently (Supplementary Table 1) in terms of making highly efficient oxygen evolution electrodes.

In particular, we prepared the corrosive solutions of Ni2+ with a wide concentration range from 10 to 200 µmol L−1, and correspondingly we fabricated a series of electrode materials by the corrosion engineering method.
The results indicated that the modified GE/EPRI method was sufficiently exact as an engineering method.
