Abstract
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 NiZnFex LDH composite by embedding Fe(OH)3 nanoparticles onto NiZn LDH nanosheets. The optimized NiZnFe12.9 LDH catalyst exhibits an overpotential of just 191 mV at 10 mA cm−2, significantly outperforming traditional OER catalysts. Additionally, it demonstrates exceptional long-term stability, maintaining a current density of 120 mA cm−2 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.
