Abstract
We investigated the relationship between the catalytic activity of ammonia synthesis and the oxygen content of catalysts using Ru/CaH2−2xOx (x = 0.00–0.44). Ru/CaH2−2xOx were enhanced as the oxygen contents increased until x = 0.29 and decreased when x was over the threshold. The apparent activation energy also decreased up to x = 0.29. Based on the kinetic analysis, oxygen suppressed the excessive electron-donation from CaH2−x(e−)x to Ru and mitigated the hydrogen poisoning over Ru.

Description
In this document, we show how the catalysts are prepared and characterized. We also compared the catalysts with those prepared by other methods.
