Co₂P-NiMoN/NF Heterostructure Nanorod Arrays as Efficient Bifunctional Electrocatalysts for Urea Electrolysis

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Electrolysis of water represents an effective method for the generation high-purity hydrogen. Nevertheless, anodic oxygen evolution reaction (OER) exhibits slow kinetics, which leads to a high electrolytic potential and induces excessive energy consumption. In this work, nickel foam-supported 3D phosphide/bimetal nitride (Co2P-NiMoN/NF) nanorod array catalyst is prepared by calcination NiMoO4, followed phosphatization Co(OH)2. The heterostructure excellent catalytic activity cathodic hydrogen (HER: η100 = 98 mV, η1000 297 mV) OER (η100 277 382 electrolysis in alkaline electrolyte, indicating its feasibility as bifunctional overall splitting (OWS). Additionally, at current density 100 mA cm-2, associated oxidation decreased roughly 160 mV when replaced with urea process (UOR), has far lower thermodynamic equilibrium potential. Density functional theory (DFT) calculations reveal that heterointerface between Co2P NiMoN enriches electronic states near Fermi level, thereby enhancing electron transfer promoting charge redistribution. This modulation precisely tunes adsorption strengths reactants during process, ultimately boosting electrocatalytic performance. A cm-2 can be attained cell voltage 1.51 V Co2P-NiMoN/NF used anode cathode cell. Notably, significantly compared (1.65 V), well previously published values. findings demonstrate efficient strategy energy-efficient production through substituting UOR electrolysis.
