Abstract

Background

We developed a novel NiFeP@CoCr-LDH hybrid electrocatalyst, synthesized via electrodeposition, to enhance the efficiency of both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER).

Methods

Characterization techniques, such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM) were employed to confirm the crystalline structure and morphology of the synthesized materials. Electrochemical techniques, including linier sweep voltammetry, electrochemical impedance spectroscopy, and chronopotentiometry, were applied to investigate the catalytic performance of synthesized electrodes.

Significant findings

The NiFeP@CoCr-LDH catalyst demonstrated remarkable electrocatalytic performance, with overpotentials of 582 mV for HER and 278 mV for OER at a current density of 10 mA cm⁻². These results surpass those of traditional catalysts, including Pt for HER and dimensionally stable anode (DSA) for OER, highlighting the high activity of the NiFeP@CoCr-LDH system. The catalyst also exhibited excellent stability over 7000 min of continuous operation.
