Abstract

Kylie A. Vincent opened a discussion of the paper by John T. S. Irvine: Do you
have a sense of what target faradaic efficiency will be needed to make viable
electrode systems for ammonia production? Will it be necessary to develop
electrodes with perfect selectivity for ammonia, or will device-engineering solu-
tions overcome these challenges?

John T. S. Irvine answered: Near 100% faradaic efficiency is needed for
ammonia and hydrogen production combined. Of this I suggest at least 50% of
the produced hydrogen stays in the ammonia. This would be sufficient to allow
engineering approaches to deliver an efficient solution.

Richard A. Catlow said: You are employing a complex quaternary oxide. Can
you say more about what properties this composition is optimising?

John T. S. Irvine replied: The composition is chosen to optimise conductivity
and stability and is directed by the relevant ion size and nominal oxygen-vacancy
content.
