Abstract

Fe3Mo3C has been prepared and its activity for ammonia synthesis was evaluated. As had been observed previously for Co3Mo3C, it was found to be inactive at 400 °C. At 500 °C activity developed and this can be related to the substitution of lattice carbon by nitrogen. Application of a simple topotactic route to prepare Ni2Mo3C from Ni2Mo3N proved unsuccessful, with the resultant carbonitride formed under optimal synthesis conditions being active for ammonia synthesis at 400 °C.
