The addition of 1 wt% Pd, Au, Ni and Cu dopants has been demonstrated to strongly alter the morphology of beta-phase molybdenum nitride prepared by treatment of MoO3 with a 3/1 H-2/N-2 mixture at 750 degrees C Furthermore, the addition of Pd significantly enhances the surface area and the formation of the nitride phase It is proposed that the facile formation of molybdenum bronzes in this system is Important in this respect. The dopants have also been observed to modify the denitridation characteristics of the beta-phase, with an overall reduction of the proportion of NH3 formed upon using a 3/1 H-2/Ar mixture with respect to the undoped sample (C) 2009 Elsevier Inc.
