The effect of a ruthenium precursor on the low-temperature ammonia synthesis activity over Ru/CeO2

The effect of a ruthenium precursor on the low-temperature ammonia synthesis activity over Ru/CeO2

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 ammon...

Zusammenfassung: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.
