摘要：

An infrared band of chemisorbed nitrogen as well as of carbon monoxide was observed in the 500 cm-1 region on Ru dispersed in a KBr matrix and promoted with K or Na. The band was unaffected by evacuation at room temperature, while it disappeared upon hydrogen treatment at 350 °C, simultaneously forming ammonia. The band shift caused by the change from K to Na as well as the above features is in accord with the behavior of the 2020 cm-1 band observed on Ru/Al2O3/K. Thus the band is assigned to the Ru{single bond}N stretching vibration of chemisorbed dinitrogen. © 1978 Academic Press, Inc. All rights of reproduction in any form reserved.
