Structural modulation of low-valent iron in LDH-derived Ni3Se4nanosheets: a breakthrough electrocatalyst for the overall water splitting reaction

Here an LDH-derived microporous Fe@Ni 3 Se 4 with enriched redox active Fe 2+ ion is reported. The same has acquired 10 mA cm −2 current density with 185 and 33 mV of overpotential value in alkaline condition with high specific activity and durability.
