Ionic conductivity and disorder in calcium and barium nitrogen hydrogen phases

Abstract

The performance of the hydride ion conductor Ca2NH is negatively affected by the incorporation of secondary anion sites. BaH2 reacted with N2 at 650 °C producing barium imide which has good electronic properties up to a certain concentration.

Hydrogen ionic conductors and ammonia conversions

“…Further system development is still required to deliver devices based upon hydride electrolytes that might be applied to ammonia electrosynthesis; however, this family of materials has already been applied successfully as catalysts in ammonia synthesis. 8…”
