ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(7), P. 7684 - 7693

Published: March 15, 2024

The exploitation of highly active, nonprecious metal bifunctional electrodes to facilitate the hydrogen evolution reaction (HER) and oxygen (OER) is essential for water electrolysis produce hydrogen, but performances are still unsatisfactory. Herein, a facile strategy was proposed fabricate three-dimensional (3D) bimetallic phosphide (NiFeP) nanoflower array on self-standing assembled MXene nanosheet film (denoted as NiFeP@MXene) structurally integrated electrode overall splitting. NiFeP@MXene with 3D hierarchical structures can be directly used an without traditional polymer binders, which significantly reduces contact resistance facilitates electron transfer at interface. Meanwhile, interfacial synergistic coupling created between conductive phosphides, favorable catalytic activity. Moreover, addition Fe improves intrinsic activity simultaneously formation flower-like more active sites. Thus, demonstrates excellent in alkaline electrolyte small overpotentials 240 122 mV drive 10 mA cm–2 current density OER HER, respectively, along superior performance compared commercial precious IrO2∥Pt/C catalyst.
