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.
