Au(III) Extraction from Water Samples Using Triazole‐Coated Novel Magnetic Adsorbents and Analysis by Inductively Coupled Plasma‐Optical Emission Spectroscopy

ChemistryOpen, EarlyView.
The synthesized magnetic nanoparticles, designated as Fe3O4@SiO2@CPTES@DAT, demonstrate effective recovery of Au(III) ions under optimized conditions at a pH of 2, utilizing 10 mg of the adsorbent, with an interaction time of 20 min. This finely tuned methodology is successfully employed to analyze various water samples regarding the recovery of Au(III)

One‐Step Aqueous Synthesis of Glycosyl Pyridinium Salts, Electrochemical Study, and Assessment of Utility as Precursors of Glycosyl Radicals Using Photoredox Catalysis

ChemistryOpen, EarlyView.
Unprotected glycosyl pyridinium salts may be accessed in a single step from the corresponding unprotected sugar in aqueous solution. Whilst meta‐ and para‐substitution is well tolerated, ortho substitution of the N‐heterocycle inhibits product formation. Electrochemical studies revealed reduction potentials in the range of −0.9 to −1.4 V.

A tribute to Professor Dr Kai A. I. Zhang: pioneering advances in metal‐free polymeric photocatalysis

Polymer International, EarlyView.
Polymeric photocatalysts have emerged as metal‐free materials with tunable structures. This review highlights the contributions of Professor Dr Kai A. I. Zhang in advancing polymer‐based photocatalysts. Abstract Polymeric photocatalysts have emerged as promising alternatives to traditional metal‐based catalysts due to their tunable properties, low cost
