Decorated high-dispersity Fe(OH)<sub>3</sub> nanoparticles on NiZn LDH nanosheets towards enhanced alkaline oxygen evolution reaction
The creation of efficient, earth-abundant electrocatalysts is crucial to address the sluggish kinetics of the oxygen evolution reaction (OER). In this study, a straightforward immersion technique is employed to fabricate a NiZnFe<sub><i>x</i></sub> LDH composite by embedding Fe(OH)<sub>3</sub> nanoparticles onto NiZn LDH nanosheets. The optimized NiZnFe<sub>12.9</sub> LDH catalyst exhibits an overpotential of just 191 mV at 10 mA cm<sup>-2</sup>, significantly outperforming traditional OER catalysts. Additionally, it demonstrates exceptional long-term stability, maintaining a current density of 120 mA cm<sup>-2</sup> for more than 125 hours. This approach fosters the advancement of materials for water splitting and hydrogen production, which are crucial for sustainable energy solutions.
