One-step synthesis of dispersed bimetallic carbides and nitrides from transition metals hexamethylenetetramine complexes

A new approach to the synthesis of molybdenum phosphide via internal oxidation and reduction route

“…It was observed earlier that the intramolecular oxidation-reduction during the thermal decomposition of transition metals hexamethylenetetramine complexes can lead to the formation of metal carbides and nitrides [15][16][17].…”

“…In recent studies, the nitrides and carbides of transition metals can be obtained on the use of hexamethylenetetramine (HMT) as a reductant [15][16][17][18]. Based on the success with the HMT route to synthesize metal nitrides and carbides, we decided to examine whether this simple procedure can also be used to produce metal phosphides.…”

Exploration on synthesis of activated carbon supported molybdenum carbide, nitride and phosphide via carbothermal reduction route

“…Recently, several papers reported that transition metals of carbides, nitrides and phosphides can be obtained from the decomposition of transition metals complexes with carbon-containing precursors under inert atmosphere [17][18][19][20][21][22][23]. As reported by Afanasiev [17], dispersed Mo 2 N with high specific surface area could be obtained from the decomposition of a molybdate HMT (HMT: hexamethylenetetramine) complex under argon atmosphere.…”

“…They suggested that this approach possessed the potential to be a general route for the preparation of bimetallic molybdenum nitrides. In addition, the HMT route was recently extended to the preparation of transition metal carbides and phosphides [19][20][21]. Another carbonaceous source route to the synthesis of binary metal nitrides, viz.…”

Surface Properties and Active Sites of Nitrided Mo/Al2O3 Catalysts for the Hydrodenitrogenation of Carbazole

“…H 2 [40][41][42] under conditions applying low heating rates, small precursor particle sizes and high space velocities. Transition metal nitrides can also be synthesized with sources of carbon and nitrogen [43] and by the CVD method with MoCl 5 , WCl 6 (WF 6 ) [44,45] and NbCl 5 with ammonia [46,47]. Additionally, phosphorus-doped tungsten oxynitride has been prepared from heteropolyanion precursors [48].…”
