Abstract

Catalysts supported on CeO₂ were prepared using various Ru precursors. The H₂-TPR profile of the catalyst was obtained beginning at −70 °C for the first time, and a previously unreported reduction peak was observed at approximately 50 °C. The lower peak temperature was associated with a higher ammonia synthesis activity.
