Abstract

The reduction of N₂ to NH₃ (N₂RR) is a globally significant reaction that is challenging due to the inertness of N₂. Transition metals can activate N₂ and mediate catalytic N₂RR, but challenges remain with respect to catalytic efficiency in terms of overpotential and selectivity. We discuss the role of the N–H bond dissociation free energy (BDFE) of metal diazenidos (M‐NNH), the first intermediates of N₂RR, in determining N2RR efficiency.
