Modulating Metal‐Nitrogen Coupling in Anti‐Perovskite Nitride via Cation Doping for Efficient Reduction of Nitrate to Ammonia

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(38)

Опубликована: Авг. 1, 2023

The complexes of metal center and nitrogen ligands are the most representative systems for catalyzing hydrogenation reactions in small molecule conversion. Developing heterogeneous catalysts with similar active metal-nitrogen functional centers, nevertheless, still remains challenging. In this work, we demonstrate that coupling anti-perovskite Co4 N can be effective modulated by Cu doping to form Co3 CuN, leading strongly promoted process during electrochemical reduction nitrate (NO3- RR) ammonia. combination advanced spectroscopic techniques density theory calculations reveal dopants strengthen Co-N bond upshifted d-band towards Fermi level, promoting adsorption NO3- *H facilitating transition from *NO2 /*NO H/*NOH. Consequently, CuN delivers noticeably better RR activity than pristine N, optimal Faradaic efficiency 97 % ammonia yield 455.3 mmol h-1 cm-2 at -0.3 V vs. RHE. This work provides an strategy developing high-performance catalyst synthesis.

Advances of Electrochemical and Electrochemiluminescent Sensors Based on Covalent Organic Frameworks

Nano-Micro Letters, Год журнала: 2023, Номер 16(1)

Опубликована: Ноя. 30, 2023

Abstract Covalent organic frameworks (COFs), a rapidly developing category of crystalline conjugated polymers, possess highly ordered structures, large specific surface areas, stable chemical properties, and tunable pore microenvironments. Since the first report boroxine/boronate ester-linked COFs in 2005, have gained popularity, showing important application prospects various fields, such as sensing, catalysis, separation, energy storage. Among them, COFs-based electrochemical (EC) sensors with upgraded analytical performance are arousing extensive interest. In this review, therefore, we summarize basic properties general synthesis methods used field electroanalytical chemistry, special emphasis on their usages fabrication sensors, ions immunosensors, aptasensors. Notably, emerged electrochemiluminescence (ECL) realm thoroughly covered along preliminary applications. Additionally, final conclusions state-of-the-art provided terms EC ECL well challenges for extending improving research applications chemistry.

Oxygen Doping Cooperated with Co‐N‐Fe Dual‐Catalytic Sites: Synergistic Mechanism for Catalytic Water Purification within Nanoconfined Membrane

Advanced Materials, Год журнала: 2024, Номер 36(30)

Опубликована: Май 14, 2024

Abstract Atom‐site catalysts, especially for graphitic carbon nitride‐based represents one of the most promising candidates in catalysis membrane water decontamination. However, unravelling intricate relationships between synthesis‐structure–properties remains a great challenge. This study addresses impacts coordination environment and structure units metal central sites based on Mantel test, correlation analysis, evolution sites. An optimized unconventional oxygen doping cooperated with Co‐N‐Fe dual‐sites (OCN Co/Fe) exhibits synergistic mechanism efficient peroxymonosulfate activation, which benefits from significant increase charge density at active regulation natural population orbitals, leading to selective generation SO 4 •− . Building upon these findings, OCN‐Co/Fe/PVDF composite demonstrates 33 min −1 ciprofloxacin (CIP) rejection efficiency maintains over 96% CIP removal (over 24 h) an average permeance 130.95 L m −2 h work offers fundamental guide elucidating definitive origin catalytic performance advance oxidation process facilitate rational design separation improved enhanced stability.
