Unleashing the Potential of Metastable Materials in Electrocatalytic Water Splitting

ACS Materials Letters, Год журнала: 2025, Номер unknown, С. 524 - 543

Опубликована: Янв. 6, 2025

Electrocatalytic water splitting is pivotal for advancing the hydrogen economy, yet conventional stable-phase catalysts are constrained by rigid crystal structures and electronic states, leading to fixed active sites, limited adaptability, sluggish kinetics. Metastable materials emerge as promising alternatives due their structural flexibility tunable properties; however, dynamic regulatory mechanisms remain underexplored. This review uniquely offers a comprehensive analysis of metastable catalysts, emphasizing how factors such size, phase structure, properties, defects, interfaces significantly enhance catalytic performance. By dissecting range (metals, alloys, oxides, sulfides, nitrides, hydroxides), we elucidate precise modulation strategies that improve efficiency stability. Practical applications highlight superior adaptability activity compared traditional catalysts. Addressing key challenges technical bottlenecks, this provides innovative insights strategic directions optimizing materials, thereby efficient sustainable energy conversion technologies.

Crystalline CoP@ Amorphous WP₂ Coaxial Nanowire Arrays as Bifunctional Electrocatalyst for Water Splitting

Small, Год журнала: 2025, Номер unknown

Опубликована: Март 13, 2025

Abstract The crystalline CoP@ amorphous WP 2 core–shell nanowire arrays are oriented grown on the Ni foam (CoP@WP /NF). shell provides more active sites, and interface charge coupling accelerates kinetic of catalytic reaction, making CoP@WP /NF catalysts excellent activity. In acidic, only 13 97 mV overpotentials needed to reach 10 mA cm −2 100 , respectively, which lowest among all reported Transition metal phosphide (TMP) catalysts, course, much lower than that Pt/C catalyst (31 at 120 ). alkaline, Hydrogen evolution reaction (HER) 68 136 mV, also most TMPs catalysts. show Oxygen (OER) performance in its OER overpotential is 254 mV. voltage /NF‐2h‖CoP@WP /NF‐2 h cell 1.37 V even Pt/C‖Ru O (1.52 V). Specially, when current density greater 150 energy consumption advantage h‖CoP@WP obvious.
