An Imidazole‐Based Halogen‐Bonded Organic Framework for the High‐Sensitive Detection of Nitrofuran Antibiotics

Chinese Journal of Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: April 25, 2025

Comprehensive Summary Nitrofuran antibiotics threaten human health and the environment due to their toxicity persistence. Their detection is challenging low concentrations interference, while fluorescence sensing offers superior sensitivity selectivity for effective monitoring. In this work, a novel halogen‐bonded organic framework, XOF‐TPEM , was introduced, constructed using an imidazole‐based ligand AIE molecule, TPEM . The framework successfully characterized by various techniques, including 1 H NMR, PXRD, XPS, FT‐IR, HRTEM, SAED, SEM EDS, confirming its excellent crystalline structure. As electron‐donating fluorophore, fluorescent demonstrates potential as selective sensor electron‐deficient nitrofuran antibiotics. Experimental results show that it exhibits high detecting nitrofurans such NFT, FZD, FLD, NFZ, with LODs of 9.7 ppb, 11.0 19.7 236.1 respectively. Mechanistic studies indicate outstanding performance attributed inner‐filter effect occurring between Through comparison pyridine‐based XOF, superiority imidazole ligands in constructing XOFs demonstrated. This study presents luminescent highlights frameworks, underscoring significant expanding functional applications.

Hollow Porous CoP–Carbon Nanocages for Hydrogen Evolution Reactions

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(11), P. 12821 - 12829

Published: May 23, 2024

Hollow porous nanocage structures with unique 3D configurations have a wide range of applications in various fields. In this work, we present convenient and efficient method for synthesizing nitrogen sulfur codoped CoP–carbon hollow nanocages by utilizing metal-organic framework compounds combination acid etching phosphating. Etching time phosphatization temperature will regulate the morphology nanocages, which, turn, affect electrocatalytic performance hydrogen evolution reaction (HER). The extensive specific surface area atom utilization can accelerate progress reactions precipitation active components. prepared N, S-codoped demonstrates excellent HER performance, exhibiting lower overpotential 137 mV at current density 10 mA cm–2 1.0 M KOH. This surpasses that most reported MOF-derived heteroatom-doped matrices. Importantly, work offers straightforward promising approach to achieving thereby advancing development highly electrocatalysts HER.

Electrochemical Detection of Furaltadone Antibiotic Drug by the Rare Earth Metal Tungstate Decorated Screen Printed Carbon Electrode

Technologies, Journal Year: 2023, Volume and Issue: 11(4), P. 105 - 105

Published: Aug. 6, 2023

Furaltadone (FLD) is an antibiotic drug that widely treated for coccidiosis, intestinal infection, and turkey blackhead. Moreover, excessive use of FLD may have some negative consequences humans domestic animals. Therefore, practical, sensitive, selective, facile detection still needed. In this exploration, a Eu2(WO4)3-nanoparticles-modified screen-printed carbon electrode was developed the low-level FLD. Hydrothermal techniques were used effectively to prepare Eu2(WO4)3 complex. Scanning electron microscopy X-ray diffraction investigations confirm Eu2(WO4)3. The results revealed well formed, crystalline, uniformly distributed. Furthermore, electrochemical behavior SPCE/Eu2(WO4) examined by differential pulse voltammetry cyclic studies. demonstrated improved electrocatalytic activity in with limit 97 µM (S/N = 3), linear range 10 nM 300 µM, sensitivity 2.1335 µA µM−1 cm−2. detected presence 500-fold excess concentrations other interfering pollutant ions. practical feasibility tested on different medicines showed adequate recovery. shows appreciable repeatability, high stability, reproducibility.
