Abstract The exploitation of highly activity oxygen evolution reaction (OER) electrocatalysts is critical for the application electrocatalytic water splitting. Triggering lattice mechanism (LOM) expected to provide a promising pathway overcome sluggish OER kinetics, however, effectively enhancing involvement remains challenging. In this study, fabrication B, Fe co‐doped CoP (B, Fe─CoP) nanofibers reported, which serve as efficient electrocatalyst through phosphorization and boronation treatment Fe‐doped Co 3 O 4 nanofibers. Experimental results combined with theoretical calculations reveal that simultaneous incorporation both B can more trigger participation in CoFe oxyhydroxides reconstructed from Fe─CoP compared incorporating only or Fe. Therefore, optimized exhibit superb low overpotentials 361 376 mV at 1000 mA cm −2 alkaline freshwater natural seawater, respectively. present work provides significant guidelines innovative design concepts development following LOM pathway.

Interface Engineering of Mo‐doped Ni₂P/Fe_xP‐V Multiheterostructure for Efficient Dual‐pH Hydrogen Evolution and Overall Water Splitting

Advanced Functional Materials, Год журнала: 2024, Номер 34(33)

Опубликована: Май 21, 2024

Abstract Developing highly effective transition metal‐based bifunctional electrocatalysts remains a tremendously challenging task for large‐scale overall water splitting. Herein, multiheterostructured Mo‐doped Ni 2 P/Fe x P electrocatalyst on NiFe foam with vacancy (denoted as Mo─Ni P‐V/NFF) is developed to serve an efficient dual‐pH electrocatalyst. Due the synergistic effect of multiple strategies (heteroatom doping, heterointerface, and vacancy), P‐V/NFF possesses remarkable hydrogen evolution reaction (HER) catalytic activity in alkaline/acidic excellent oxygen (OER) alkaline media, along encouraging durability. The mechanisms improved electrocatalytic combining multicharacterizations density functional theory (DFT) calculations are elucidated. Specifically, X‐ray absorption fine structure experimental analysis confirms that Mo doping can optimize electronic In situ Raman spectroscopy demonstrates evolved oxyhydroxides real active substances OER. DFT reveal conductivity as‐prepared samples be enhanced through strategy synergy. Moreover, HER process, not only reduce binding energy near zero but also enhance H O dissociation *OH desorption. OER verify interface engineering adsorption rate‐determining step, achieving lowest theoretical overpotential.
