The electrochemical reduction of oxidized nitrogen species enables a pathway for the carbon neutral synthesis of ammonia (NH3 ). The most oxidized form of nitrogen, nitrate (NO3 - ) can be reduced to NH3 via the electrocatalytic nitrate reduction reaction (NO3 RR), which has been demonstrated at high selectivity. However, to make NH3 synthesis cost-competitive with current technologies, high NH3 partial current densities (jNH3 ) must be achieved to reduce the levelized cost of NH3 . Here, we leverage the high NO3 RR activity of Fe-based materials to synthesize a novel active particle-active support system with Fe2 O3 nanoparticles supported on atomically dispersed Fe-N-C...
