Schematic illustrations of the formation and microstructure of the electrodes. a The specific reactions happened during the corrosion of iron substrates; and b the formation of grain boundary-enriched layered double hydroxide (LDH) nanosheet arrays on the surface of iron substrates. A representative crystal structure of LDH is also shown in b
