Two Novel Viologen/Polyoxometalate‐Based Compounds for the Efficient Photocatalytic Reduction of Cr (VI) Under Visible Light Irradiation

Applied Organometallic Chemistry, Journal Year: 2025, Volume and Issue: 39(2)

Published: Jan. 15, 2025

ABSTRACT Designing efficient photocatalyst has attracted extensive attention for treating polluted wastewater containing Cr (VI). In this work, two viologen/polyoxometalate (POM)‐based compounds were synthesized, [Ni (mimb) 2 (H O) 4 (β‐Mo 8 O 26 )]·4H ( 1 ) and [Zn (mimb = 1‐((3,5‐dimethylisoxazol‐4‐yl)methyl)‐[4,4′‐bipyridin]‐1‐ium), through a hydrothermal method investigated their ability of photocatalytic reduction The structures 1–2 characterized by single‐crystal X‐ray diffraction, revealing that both possess zero‐dimensional (0D) structure can form one‐dimensional (1D) chain hydrogen bondings. Photocatalytic experiments demonstrate compound superior performance compared to . Under optimal conditions (pH 2, 15 mg catalysts, 10 L −1 (VI) concentration), completely reduce within 20 min, while requires 30 min. Compounds also show good stability after reaction, maintain high activity five reaction cycles. Additionally, the mechanism was studied, free radical scavenging its main active species are e − , h + ˙O nitroblue tetrazolium (NBT) further confirm crucial role in process. activity, stability, recyclability viologen/POM‐based suggest potential application treatment

Chiral Sensing of Tryptophan Enantiomers Based on the Enzyme Mimics of β-Cyclodextrin-Modified Sulfur Quantum Dots

ACS Sensors, Journal Year: 2023, Volume and Issue: 8(11), P. 4264 - 4271

Published: Nov. 2, 2023

Chiral recognition of amino acid plays a significant role in pharmaceutical, medical, and food science. This study describes chiral sensing system β-cyclodextrin (β-CD)-coated sulfur quantum dots (CD-SQDs) for the selective fluorescence tryptophan (Trp) enantiomers. CD-SQDs were prepared by facile assembly fission method could selectively recognize L-Trp different binding ability between L/D-Trp β-CD. The inclusion stereoselective catalysis enzyme mimics cause increased intensity CD-SQDs, which has linear response ranging from 10 to 500 nM detection limit as 2.3 nM. also show great selectivity commercial compound injection. provide an effective enantiomers based on catalytic activity nanoenzymes.
