Nitrogen fixation using metallic lithium nanoparticles formed by electrospray deposition.

ABSTRACT: Multiphase reduction of ambient dinitrogen (N₂) was observed during the deposition of charged or uncharged aqueous microdroplets containing a lithium salt pre-catalyst onto conducting or inert surfaces to yield mixed lithium nanoparticles. We propose that this method leverages the high electric fields and partial solvation of ions at the gas-water-solid interface to enhance reaction rates and perform normally moisture-sensitive chemistry in aqueous droplets. Ammonia (NH₃) is formed and Li⁺ is regenerated from the hydrolysis of transient lithium nitride Li₃N, constituting a complete catalytic cycle. The ammonia is captured in situ using formaldehyde to yield hexamethylenetetramine, a solid nitrogenous fuel. By measuring product formation wi
