Key Points

The aim is to synthesize and test the catalytic properties of different phases in the Fe–Co–Mo–N system.
Synthetic methods were employed to create five phases of Fe3–xCoxMo3N.
Characterization was done using energy-dispersive X-ray spectroscopy, hot gas extraction analyses, and X-ray diffraction.
Catalytic activity for ammonia decomposition was assessed and compared among the synthesized phases.
Co3Mo3N and Fe3Mo3N demonstrated higher catalytic activity compared to the solid solutions.
The characterization techniques confirmed the composition and structure of the synthesized phases.

Implication

This investigation reveals catalytic activity for ammonia decomposition in iron-cobalt-molybdenum phases, suggesting potential applications.

Abstract

Five phases of Fe3–xCoxMo3N were synthezised and characterized by energy-dispersive X-ray spectroscopy, hot gas extraction analyses and X-ray diffraction. The catalytic activity for the decomposition of ammonia was investigated. The data was compared with the results for Fe3Mo3N. Co3Mo3N and Fe3Mo3N show a higher activity than the solid solutions.
