研究了铁、钴、氮二化物在H-2 /Ar条件下的脱氮行为。发现氮化铁在400℃时损失了70%以上的氮含量，氮化钴在250℃时完全脱氮，氮化铼在350℃时损失了近90%的氮。此外，对氨解法制备的Co-Re-4进行了研究，在400℃H-2/Ar条件下，该材料仅损失了微量的NH3。与H-2/N-2的反应证明了它是一种活性的常压氨合成催化剂。
The denitridation behaviour of binary iron, cobalt and rehnium nitrides under H-2 /Ar has been investigated. The iron nitride was found to lose over 70 % of its as prepared nitrogen content at 400 A degrees C. The cobalt nitride was completely denitrided at 250 A degrees C. Rhenium nitride lost close to 90 % of its nitrogen at 350 A degrees C. In addition, Co-Re-4 prepared by ammonolyis was investigated, whilst only traces of NH3 were lost from this material under H-2/Ar at 400 A degrees C, with H-2/N-2 it proved to be an active ambient pressure ammonia synthesis catalyst in accordance with previous literature.
