Abstract
Despite this abundance, atmospheric nitrogen is chemically inert due to the presence of a strong triple bond (N≡N) that has a high bond dissociation energy of about 941 kJ/mol. This inertness renders N2 unavailable for direct assimilation by most living organisms, thereby necessitating its conversion into reactive nitrogen species such as ammonia (NH3), nitrate (NO3−), or nitrite (NO2−), which are essential for the biosynthesis of amino acids, nucleotides, and other vital biomolecules. The process by which inert nitrogen gas is converted into ammonia is termed nitrogen fixation, and among the strategies employed to achieve this transformation, Nitrogen Reduction Reactions (NRR) have emerged as a focal point of research, especially in the context of sustainable and environmentally friendly chemistry.Traditionally, the conversion of nitrogen gas into ammonia on an industrial scale has been accomplished through the Haber–Bosch process, developed in the early 20th century.
