WebFor supported nitrides, XRD data revealed the presence of the hexagonal FeWN2 mixed phase for bimetallic catalysts and W2.2N2 and Fe3N for each monometallic catalyst. In contrast, for bulk monometallic W nitride it was found that W2N was the monometallic crystalline phase obtained. Texture analysis showed that specific surface area of catalyst ...
