“…Comparing the activities of the three catalysts clearly demonstrates that the incorporation of Ni into the molybdenum nitride in the form of MCM41-supported Ni 2 Mo 3 N catalyst resulted in a considerable increase in hydrogenation activity. This result is very similar to that reported by others, in which Ni 2 Mo 3 N catalyst was more active than Mo 2 N catalyst for HDS and HDN reactions [11,12], and indicates that such bimetallic molybdenum nitrides are more suitable for use as hydrotreating catalysts than monometallic molybdenum nitride. It is confirmed that the Ni 2 Mo 3 N is the unique existing species on the support and the better hydrogenation activity of Ni 2 Mo 3 N catalyst than Ni catalyst probably owes to the special structure of Ni 2 Mo 3 N, which contains net of nickel atoms, the holes in which are filled by Mo 6 N octahedral [17].…”

“…Transition metal nitrides have also been tested for hydrotreatments [7][8][9][10][11][12]. However, most studies in this area have concentrated on monometallic transition metal nitrides, and relatively few bimetallic nitrides have been studied.…”

“…Así, se les ha encontrado utilidad como materiales estructurales, como herramientas de corte, o como catalizadores, entre otras. En particular, el nitruro de molibdeno, además de las propiedades antes mencionadas, fue propuesto en 1981 como un compuesto superconductor [8][9] y, recientemente, ha sido mostrado en la bibliografía como poseedor de una alta actividad catalítica [10][11][12][13][14][15][16][17][18][19] .Por otra parte, el estudio de los nitruros ternarios de los metales de transición, empezó a cobrar relevancia a partir de 1993, cuando se publicó la obtención del FeWN 2 [20] , ya que estos compuestos poseen propiedades comparables o incluso superiores a las de los nitruros binarios. No obstante, si el conocimiento de las propiedades fisicoquímicas y de las estructuras de los nitruros binarios dista mucho de ser completo, con respecto a los nitruros ternarios apenas si existen algunos estudios.…”

“…No obstante, si el conocimiento de las propiedades fisicoquímicas y de las estructuras de los nitruros binarios dista mucho de ser completo, con respecto a los nitruros ternarios apenas si existen algunos estudios. A pesar del gran potencial tecnológico sólo un pequeño número de compuestos están identificados hoy en día.Las rutas de síntesis más utilizadas para este tipo de nitruros son: amonolisis del óxido mixto, como es el caso del Co 3 Mo 3 N, a partir de CoMoO 4 ; ó, a partir de mezclas de óxidos, como el caso del Ni 2 Mo 3 N, a partir de NiMoO 4 y MoO 3 [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] . Otra ruta utilizada ha sido la reacción entre el nitruro de molibdeno y el metal [27] , por amonolisis del nitrato del metal soportado en el nitruro de molibdeno [12] y, por último, amonolisis de una mezcla de los cloruros metálicos [28] .…”
