Replacing the oxygen evolution reaction (OER) with urea oxidation (UOR) in conjunction hydrogen (HER) offers a feasible and environmentally friendly approach for handling urea-rich wastewater generating energy-saving hydrogen. However, deactivation detachment of active sites powder electrocatalysts reported hitherto present significant challenges to achieving high efficiency sustainability production. Herein, self-supported bimetallic nickel manganese metal–organic framework (NiMn-MOF) nanosheet its derived heterostructure composed NiMn-MOF decorated ultrafine Pt nanocrystals (PtNC/NiMn-MOF) are rationally designed. By leveraging synergistic effect Mn Ni, along strong electronic interaction between PtNC at interface, optimized catalysts (NiMn-MOF PtNC/NiMn-MOF) exhibit substantially reduced potentials 1.459 −0.129 V reach 1000 mA cm–2 during UOR HER. Theoretical calculations confirm that Mn-doping heterointerface regulate d-band center catalyst, which turn enhances electron transfer facilitates charge redistribution. This manipulation optimizes adsorption/desorption energies reactants intermediates both HER UOR, thereby significantly reducing energy barrier rate-determining step (RDS) enhancing electrocatalytic performance. Furthermore, degradation rates PtNC/NiMn-MOF (96.1%) (90.3%) higher than those Ni-MOF most advanced catalysts. work provides valuable insights designing applicable treatment

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.
