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).
