In-situ electrochemical control of the catalytic activity of platinum for the propene oxidation

The development of electrochemical promotion necessitates new solid electrolytes with improved ionic conduction at lower temperatures. Among them, Na Super Ionic Conductor (NaSICon), i.e. Na3Zr2Si2PO12, is a promising Na+ conducting electrolyte. The Pt/NaSICon system was evaluated for the electrochemical promotion of propene combustion both with large excess of oxygen (for volatile organic contaminants, VOCs, abatement) and near the stoichiometry (for energy production).
