Noble Metal Nanoparticles Anchored on Transition Metal Phosphides for Effective pH‐Universal Hydrogen Evolution

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Апрель 30, 2025

Constructing electrocatalysts with high activity and low precious metal content is essential for achieving efficient hydrogen production in pH-universal overall water splitting. Herein, five types of noble anchored transition phosphides are analyzed by theoretical derivation. Based on the calculation results, a suitable hybrid screened out Pt nanoparticles CoP nanowires (Pt─CoP) via robust Pt─P─Co bonds. This strong synergy between through interfacial bonds optimizes adsorption key intermediates evolution reaction (HER) wide pH range from 0 to 14. Furthermore, interaction accompanied delicate structure reduces charge transfer resistance, creates abundant active sites, enhances catalyst durability, while facilitating site exposure electron/mass during HER process. Accordingly, synthesized Pt─CoP exhibits overpotentials 79, 26, 18 mV at 10 mA cm-2 acidic, neutral, alkaline media HER, respectively, superior commercial Pt/C benchmarks most reported electrocatalysts. work paves new clue exploit low-Pt-loading HER.

In the present work, synthesis and decomposition of low-dimensional materials from a Ni15Mo25W10C50 system produced by mechanical alloying was reported. During milling process, resultant phases were WMoC NiC, after sintering quenching, MoNi3, WMo, Ni4W, WC, MoNi Mo2C found. The samples analyzed X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy. Nanotubes with lengths ranging 500 nm to 2 μm, spheres novelty globular particles sizes 40 600 as well “petal-like” estructure observed. results revealed formation microstructure morphology similar spinodal followed sequence invariant reactions leading production modulated novel branched structures. We proposes theoretical mechanism that is associated structure observed quenching.
