Charge Self-Regulation at the Interface Engineering of the Metallic Heterostructure NiCoP@Co₃S₄ for Efficient Alkaline Overall Water Splitting

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Май 7, 2025

Developing heterostructures with high electrical conductivity and appropriate adsorption strength for oxygen intermediates is a crucial strategy to reduce the energy consumption of overall water splitting (OWS) enhance economic viability hydrogen energy. This article proposes novel metallic heterostructure (NiCoP@Co3S4) that in situ grown on nickel foam. The composite NiCoP Co3S4 not only promotes effective charge transfer heterojunction accelerates kinetics evolution reaction (HER) (OER) but also optimizes electronic structure catalyst through interface engineering. Density functional theory (DFT) calculations demonstrate formation significantly increases density states near Fermi level (EF), thereby enhancing conductivity. Moreover, d-band center NiCoP@Co3S4 shifts closer EF, which enhances binding catalyst's active sites. shift lowers activation thus catalytic process. Experimental results show exhibits excellent performance both HER (η10 = 62 mV) OER 203 mV). An electrolyzer composed electrodes requires potential 1.48 V achieve current 10 mA cm-2. Additionally, it demonstrates good stability over 100 h testing, outperforming Pt/C || RuO2 (1.51 V@10 cm-2). work provides an approach achieving efficient production at low overpotentials self-regulation heterostructures, offering new insights design non-noble metal-based electrocatalysts.

Electron Islands‐Induced Interface Engineering in FeP@NiCoP/Mo₄P₃ for Efficient Hydrogen Evolution Catalysis

Опубликована: Май 24, 2025

Abstract This study employs an “electron island” micro‐interface engineering strategy to construct a NiCoP/Mo 4 P 3 heterostructured catalytic system on FeP substrate via synergistic hydrothermal synthesis and low‐temperature phosphorization approach. The unique open hierarchical architecture provides atomic‐scale anchoring sites for small‐sized Mo quantum dots (QDs), forming high‐density island‐substrate” network, which drastically increases the population of active between two phases. Concurrently, discretely distributed QDs induce interfacial charge polarization through confinement effects, generating robust built‐in electric field at heterointerfaces that drives directional electron migration. Density functional theory (DFT) calculation shows interaction NiCoP can effectively manipulate electronic regulate H* adsorption energy, further decreasing Gibbs free energy (ΔG ). FeP@NiCoP/Mo make full use generated interface, give play properties heterogeneous structures, ensures significantly enhanced hydrogen evolution reaction (HER) efficiency excellent long‐term stability in alkaline water complicated seawater environments. work guidance direction maximize interface effect designing efficient stable catalysts.
