Abstract

Nitrogen chemisorption on supported Fe−Co, Fe−Mo and Co−Mo catalysts for ammonia synthesis has been studied. No considerable effect of carrier (carbon fibers) on nitrogen chemisorption has been found. It is shown that for these samples chemisorbed nitrogen has various dissociative forms.

Abstract

Изучена хемосорбция азота на нанесенных Fe−Co, Fe−Mo и Co−Mo аммиачных катализаторах. Не было обнаружено влияние носителя (углеродного волокна) на хемосорбционные характеристики азота. Показано, что для данных образцов хемосорбированный азот существует в различных по энергии диссоциативных формах.
