Doping Mo Triggers Charge Distribution Optimization and P Vacancy of Ni₂P@Ni₁₂P₅ Heterojunction for Industrial Electrocatalytic Production of Adipic Acid and H₂

Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Synchronous electrosynthesis of value-added adipic acid (AA) and H2 is extremely crucial for carbon neutrality. However, accomplishing the preparation AA at large current density with high selectivity still challenging. Herein, a robust Mo-doped Ni2P@Ni12P5 heterojunction more P vacancies on Ni foam proposed simultaneous electrooxidation cyclohexanol (CHAOR) to hydrogen evolution reaction (HER) density. Combined X-ray photoelectron spectroscopy, absorption fine structure, electron spin resonance confirm that Mo incorporation induces charge redistribution Ni2P@Ni12P5, where adjusts electrons from P, triggers vacancies. Further experimental theoretical investigations reveal d-band center upshifted, optimizing adsorption energies water electron-rich site boosting HER activity. Besides, Ni3+ generated electron-deficient induced by Mo, alongside OH* triggered concurrently promote CHA dehydrogenation C─C bond cleavage, decreasing energy barrier CHAOR. Consequently, two-electrode flow electrolyzer achieves industrial (>230 mA cm-2) 85.7% yield, 100% Faradaic efficiency production. This study showcases an bifunctional electrocatalyst production productivity.

Transforming Red Phosphorus Photocatalysis: Dual Roles of Pre‐Anchored Ru Single Atoms in Defect and Interface Engineering

Angewandte Chemie, Год журнала: 2024, Номер 136(45)

Опубликована: Июль 15, 2024

Abstract Crystalline red phosphorus (CRP), known for its promising photocatalytic properties, faces challenges in hydrogen evolution (PHE) due to undesired inherent charge deep trapping and recombination effects induced by defects. This study overcomes these limitations through an innovative strategy integrating ruthenium single atoms (Ru 1 ) within CRP simultaneously repair the intrinsic vacancy defects serve as uniformly distributed anchoring sites a controllable growth into nanoparticles NP ). Hence, highly functionalized with Ru 1‐NP /CRP) concerted regulating electronic structures promoting interfacial transfer has been achieved. Advanced characterizations unveil pioneering dual role of pre‐anchored (analogous “Tai Chi” principle) transforming photocatalysis. The regulations on surface minimize detrimental trapping, resulting prolonged lifetime active charges. With well‐distributed situ sites, constructed robust “bridge” that connects facilitates constructive transfer. Ultimately, synergistic effect endows /CRP exceptional PHE rate 3175 μmol h −1 g , positioning it one most efficient elemental‐based photocatalysts available. breakthrough underscores crucial pre‐anchoring metal at defect catalysts enhancing sustainable production.

Assessing the Structural Diversity of Form II Red Phosphorus via Stepwise Crystal Structure Search

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(38), С. 26369 - 26378

Опубликована: Сен. 16, 2024

Recently, the long less-known Form II red phosphorus (RP) (viz. Type RP) was ascertained by state-of-the-art 3-dimensional electron diffraction technique with a triclinic lattice, completely distinct from other known elemental and leaving atomic coordinates not determined. The cell composed of ∼250 atoms might exceed capacity current readily available crystal structure search packages, which have been widely applied to systems several tens atoms. Besides, mistaking RP for violet is still surprisingly common in studies on allotropic due misinterpretations JCPDS card #00-044-0906. Herein, reproducing annealing synthesis relaxation structures obtained literature, we verified two former be wrong explained how occurred. Then, basis experimental lattice data, provided possible models containing positions nearly exhaustive high-throughput stepwise approach optimized molecular mechanics, machine-learned force field, density functional theory succession. energetic stability found rank between white black phosphorus, similar nanorod modifications.
