Abstract

The denitridation behaviour of binary iron, cobalt and rehnium nitrides under H2 -Ar has been investigated. The iron nitride was found to lose over 70 % of its as prepared nitrogen content at 400 °C. The cobalt nitride was completely denitrided at 250 °C. Rhenium nitride lost close to 90 % of its nitrogen at 350 °C. In addition, Co-Re4 prepared by ammonolyis was investigated, whilst only traces of NH3 were lost from this material under H2-Ar at 400 °C, with H2-N2 it proved to be an active ambient pressure ammonia synthesis catalyst in accordance with previous literature.
