Characterizing Hydrogen Evolution Reaction of NiCoFe-LDH@NiCo₂O₄ Heterostructured Electrocatalyst for Hydrogen Generation

Abstract:

This paper introduced a low-overpotential heterostructured NiCoFe-LDH@NiCo₂O₄ electrocatalyst for hydrogen evolution reaction (HER). The hecterostructure was synthesized by the hydrothermal method. The electrocatalyst was coated on a Nikel foam (NiCoFe-LDH@NCO/NF) to make the electrodes. The synergistic effects between NiCoFe-LDH and NiCo₂O₄, coupled with the unique structure and high electrochemically active surface area, resulted in high-performance HER electrocatalytic activity. The HER performance of NiCoFe-LDH@NCO/NF electrode exhibited a low overpotential of 147 mV at a current density of 50 mAcm⁻² and a Tafel slope of 83 mVdec⁻¹. The abundance and low cost of the constituent materials make NiCoFe-LDH@NCO/NF a promising candidate for practical applications in water splitting for sustainable hydrogen production.
