Synthesis of Hollow Leaf-Shaped Iron-Doped Nickel–Cobalt Layered Double Hydroxides Using Two-Dimensional (2D) Zeolitic Imidazolate Framework Catalyzing Oxygen Evolution Reaction

Layered double hydroxides (LDHs) have been reported as one of the most effective materials for oxygen evolution reaction (OER) catalysts, which are prone to hydrolysis and oxidation under OER conditions. Metal–organic frameworks (MOFs) porous with high crystallinity internal surface area. The design LDHs based on MOFs has attracted increasing attention owing their area, exposed catalysis sites, fast charge/mass transport kinetics. Herein, we report a novel approach fabricate leaf-shaped iron-doped nickel–cobalt LDH (L-Fe-NiCoLDH) derived from two-dimensional (2D) zeolitic imidazolate framework leaf-like morphology (ZIFL). Iron doping played significant role in enhancing specific affecting performance. L-Fe-NiCoLDH showed performance an overpotential 243 mV at 10 mA cm−2 durability after 20 h. leaf offers tremendous potential improving efficiency.
