In situ Generation of Fluoride Catalysts for CO2‐to‐Formic Acid Conversion With Silicon Reducing Agent

open access: yesChemistry – A European Journal, Volume 32, Issue 32, 24 August 2026.
Reductive conversion of CO2 to formic acid with waste silicon reducing agent catalyzed by in situ generation of active fluoride species from a tertiary amine, protonic acid, and simple inorganic fluoride salt, such as KF and NaF. ABSTRACT The activation and catalytic reduction of carbon dioxide (CO2) using silicon‐based reducing agents is an important ...

Mechanochemical Degradation and Fluoride Recovery of Perfluorosulfonic Acid Polymer Membrane

open access: yesChemSusChem, Volume 19, Issue 15, 14 August 2026.
The mechanochemical degradation of a perfluorosulfonic acid polymer (PFSA) used in fuel cells, was studied. The products were characterized by various techniques including nuclear magnetic resonance spectroscopy, scanning electron microscopy−energy dispersive X‐ray spectroscopy and liquid chromatography−mass spectrometry.
