Air‐Stable Mo ₂ N as a Nitrogen Source for Alcohol Amination via Hydrogen Spillover Activation

Transition metal nitrides (TMNs) are widely used as functional materials and catalysts, yet their potential as a feedstock for organonitrogen synthesis remains unexplored. Herein, we propose an alternative route to achieve amine production using molybdenum nitride as the nitrogen source. We prepare Mo 2 N reactant by hexamethylenetetramine‐assisted pyrolysis, and the as‐prepared surface is initially passivated by a protective layer composed of graphene oxide and MoO 3 , which enhances the air stability and prevents the loss of lattice nitrogen reactivity. The incorporation of extra active metal sites enables H 2 dissociation at these centers, and the active hydrogen species remove the surface passivation layer through spillover, enabling the nitride activation. For the octanol amination, the activated Mo 2 N enables a tri‐octylamine yield of 369.6 μmol/g Mo2N with almost 100% N‐basis selectivity under 250 °C and 10 bar H 2 .
