HDS and HDN activity of (Ni,Co)Mo binary and ternary nitrides prepared by decomposition of hexamethylenetetramine complexes

[Display omitted] ► Highly dispersed Mo 2N, Co 3Mo 3N and Ni 3Mo 2N were prepared from HMTA complexes. ► Co(Ni)Mo nitrides are highly active HDN catalysts in the absence of sulfur. ► Sulfidation leads to surface segregation of MoS 2 and loss of activity. ► Soft oxidation and resulfidation allows par...
