Abstract Designing cost‐effective electrocatalysts with fast reaction kinetics and high stability is an outstanding challenge in green hydrogen generation through overall water splitting (OWS). Layered double hydroxide (LDH) heterostructure materials are promising candidates to catalyze both oxygen evolution (OER) (HER), the two OWS half‐cell reactions. This work develops a facile hydrothermal route synthesiz hierarchical MoS 2 @NiFeCo‐LDH @NiFeCo‐Mo(doped)‐LDH electrocatalysts, which exhibit extremely good OER HER performance as witnessed by their low IR‐corrected overpotentials of 156 61 mV at current density 10 mA cm −2 under light assistance. The @NiFeCo‐Mo(doped)‐LDH‐MoS cell achieves voltage 1.46V during light‐assisted electrolysis. Both exhibited exceptional industrially relevant conditions, maintaining 1 A minimal alterations potential performance. experimental computational results demonstrate that doping LDH matrix high‐valence Mo atoms quantum dots improves electrocatalytic activity 1) enhancing electron transfer, 2) making electrocatalyst metallic, 3) increasing number active sites, 4) lowering thermodynamic overpotential, 5) changing mechanism. Overall, this synthesis method design highly stable electrocatalysts.

Small, Год журнала: 2025, Номер unknown

Опубликована: Фев. 21, 2025

Abstract Layered double hydroxides (LDHs) exhibit great potential in electrocatalytic water splitting due to the unique 2D feature and an adjustable structure composed of different metal centers. In addition, LDHs have advantage being inherently inexpensive compared other catalysts good stability splitting. Up now, numerous methods been put forward improve activity splitting, a comprehensive introduction comb fabrication modification strategies is helpful for followers get clear vein carry out efficient manipulation development high promising catalysts. this review, basic principles electrolysis, evaluation indexes are introduced first, then properties commonly utilized introduced. After that, oxygen evolution reaction (OER), hydrogen (HER), overall (OWS) performance LDHs‐based analyze merits shortcomings compared. Based on this, advanced improving give brief prospect materials electrocatalysis.
