Degradation of macrolide antibiotic in water by heterogeneous photocatalysis

open access: yesRevue des Énergies Renouvelables, 2017
Le présent travail porte sur la dégradation photocatalytique d’un antibiotique macrolide nommé tylosine (TYL) dans un réacteur batch en utilisant du dioxyde de titane en poudre (TiO2) et une irradiation artificielle 'lampe 9W-UV.

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

open access: yesChemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

Evaluation of the Relationship between Bulk Organic Precursors and Disinfection Byproduct Formation for Advanced Oxidation Processes [PDF]

open access: yes, 2015
Advanced oxidation processes (AOPs) are gaining traction as they offer mineralization potential rather than transferring contaminants between media. However, AOPs operated with limited energy and/or chemical inputs can exacerbate disinfection byproduct ...

Insights into the Photocatalytic Arene Bromination Enabled by Cs2AgBiBr6 Microparticles

open access: yesChemistry – A European Journal, EarlyView.
A sustainable photocatalytic bromination of electron‐rich arenes is enabled by low‐toxicity Cs2AgBiBr6 double‐perovskite microparticles using HBr as an atom‐economical bromine source. Surface‐derived bromine radicals drive highly selective mono‐bromination under mild conditions.

Self-cleaning Properties of Thin Printed Layers of Titanium Dioxide [PDF]

open access: yes, 2012
Tenké vrstvy oxidu titaničitého byly imobilizovány na sodnovápenatá skla a skelný uhlík použitím jak techniky materiálového tisku tak metodou chemického napařování. Pro přípravu titaničitých solů byly použity metody sol-gelu a nebo hydrotermální syntézy.

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

open access: yesChemistry – A European Journal, EarlyView.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...
