Abstract Interfacial electronic structure modulation of nickel‐based electrocatalysts is significant in boosting energy‐conversion‐relevant urea oxidation reaction (UOR). Herein, porous carbon nanofibers confined mixed Ni‐based crystal phases Ni 2 P and NiF are developed via fluorination phosphorization coated nanofiber (Ni P/NiF /PCNF), which possess sufficient mesoporous optimized Gibbs adsorption free energy by phase‐induced charge redistribution. This novel system further reduces the barrier improves activity addressing challenges low intrinsic activity, difficulty active site formation, insufficient synergism. A considerably high current density 254.29 mA cm −2 reached at 1.54 V versus reversible hydrogen electrode on a glass electrode, cell voltage requires 1.39 to get 10 generation, with very good stability, about 190 mV less than that traditional water electrolysis. The facile phase formation transfer ability induced asymmetric redistribution found interface, where molecules tend bond atoms surface heterojunction, rate‐determining step changed from CO desorption fourth H‐atom deprotonation. work reveals catalyst interfacial polarity for energy‐relevant catalysis reactions.

Multicomponent Interface and Electronic Structure Engineering in Ir-Doped CoMO₄–Co(OH)₂ (M = W and Mo) Enable Promoted Oxygen Evolution Reaction

Inorganic Chemistry, Год журнала: 2024, Номер 63(34), С. 16037 - 16046

Опубликована: Авг. 9, 2024

The core principles of multicomponent interface and electronic structure engineering are essential in designing high-performance catalysts for the oxygen evolution reaction (OER). However, combining these aspects within a catalyst is significant challenge. In this investigation, novel approach involving development hybrid Ir-doped CoMO4–Co(OH)2 (M = W Mo) hollow nanoboxes was introduced, enabling remarkably efficient water oxidation electrocatalysis. Constructed from ultrathin nanosheet-assembled nanoboxes, structures boast wealth active centers intermediate species, which turn enhance both charge transfer mass transport capabilities. Moreover, compelling synergistic effects arising interaction between CoMO4 Co(OH)2 significantly bolster OER electrocatalysis by facilitating electron transfer. introduction Ir atoms serves to strategically adjust structure, fine-tune its state, operate as electrocatalysis, thus diminishing overpotential. This configuration results Ir-CoWO4–Co(OH)2 Ir-CoMoO4–Co(OH)2 exhibiting impressively low overpotentials 252 261 mV, respectively, 10 mA cm–2. Utilized conjunction with Pt/C two-electrode system overall splitting, mere 1.53 V cell potential needed achieve desired cm–2 current density.
