The evolution of nitrogen fixation undoubtedly altered nearly all corners the biosphere, given essential role in synthesis biomass. To date, there is no unified view on what planetary conditions gave rise to or how these have sustained it evolutionarily. Intriguingly, concentrations metals that nitrogenases require function changed throughout Earth's history. In this review, we describe interconnection metal and cycles with nitrogenase importance ancient ecology formation modern cycle. We argue exploration cycle's deep past will provide insights into humanity's immediate environmental challenges centered availability.

The electrocatalytic reduction of nitrate (NO3- ) to nitrogen (N2 is an environmentally friendly approach for efficient N-cycle management (toward a nitrogen-neutral cycle). However, poor catalyst durability and the competitive hydrogen evolution reaction significantly impede its practical application. Interface-chemistry engineering, utilizing close relationship between surface/interface microenvironment electron/proton transfer process, has facilitated development catalysts with high intrinsic activity physicochemical durability. This study reports synthesis nitrogen-doped carbon-coated rice-like iron nitride (RL-Fe2 N@NC) electrocatalyst excellent nitrate-reduction (high N2 selectivity (≈96%) NO3- conversion (≈86%)). According detailed mechanistic investigations by in situ tests theoretical calculations, strong hydrogenation ability enhanced enrichment system synergistically contribute rapid nitrogen-containing species, increasing reducing occurrence competing hydrogen-evolution side reaction. Moreover, RL-Fe2 N@NC shows stability, retaining good -to-N2 electrocatalysis more than 40 cycles (one cycle per day). paper could guide interfacial design Fe-based composite nanostructures reduction, facilitating shift toward neutrality.

Carbon and nitrogen fixation strategies are regarded as alternative routes to produce valuable chemicals used energy carriers fertilizers that traditionally obtained from unsustainable energy-intensive coal gasification (CO CH4), Fischer–Tropsch (C2H4), Haber–Bosch (NH3) processes. Recently, the electrocatalytic CO2 reduction reaction (CO2RR) N2 (NRR) have received tremendous attention, with merits of being both efficient store renewable electricity while providing preparation fossil-fuel-driven reactions. To date, development CO2RR NRR processes is primarily hindered by competitive hydrogen evolution (HER); however, corresponding for inhibiting this undesired side still quite limited. Considering such complex reactions involve three gas–liquid–solid phases successive proton-coupled electron transfers, it appears meaningful review current improving product selectivity in light their respective mechanisms, kinetics, thermodynamics. By examining developments understanding catalyst design, electrolyte engineering, three-phase interface modulation, we discuss key NRR: (i) targeting molecularly defined active sites, (ii) increasing local reactant concentration at (iii) stabilizing confining intermediates.
