Catalyst-Free Nitrogen Fixation by Microdroplets through a Radical-Mediated Disproportionation Mechanism under Ambient Conditions

. Supported by these findings and theoretical calculations, we propose a radical-mediated nitrogen disproportionation mechanism. Simulations of naturally occurring condensed microdroplets also demonstrated nitrogen redox fixation. This microdroplet-based method not only offers a potential pathway for nitrogen fixation in practical applications and sustainable development but also deepens our understanding of the natural nitrogen cycle.
