Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide

open access: yesChemistry – A European Journal, EarlyView.
Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

open access: yesChemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Silica Coating Enhances the PFAS Photocatalytic Properties of Boron Nitride

open access: yesCleanMat, EarlyView.
A coating of 6 wt% SiO2 effectively covered the edges of BN, which lowered BN hydrolysis and increased PFOA photodegradation. ABSTRACT Boron nitride (BN) has recently emerged as a promising material capable of breaking down toxic perfluorooctanoic acid (PFOA) and other per‐ and polyfluoroalkyl substances (PFAS) through photocatalysis. However, chemical
