To restore the natural nitrogen cycle (N-cycle), artificial N-cycle electrocatalysis with flexibility, sustainability, and compatibility can convert intermittent renewable energy (e.g., wind) to harmful or value-added chemicals minimal carbon emissions. The background of such N-cycles, as fixation, ammonia oxidation, nitrate reduction, is briefly introduced here. discussion emerging nanostructures in various conversion reactions focused on architecture/compositional design, electrochemical...
NiCo2 O4 nanowire array on carbon cloth (NiCo2 /CC) is proposed as a highly active electrocatalyst for ambient nitrate (NO3- ) reduction to ammonia (NH3 ). In 0.1 m NaOH solution with NaNO3 , such /CC achieves high Faradic efficiency of 99.0% and large NH3 yield up 973.2 µmol h-1 cm-2 . The superior catalytic activity comes from its half-metal feature optimized adsorption energy due the existence Ni in crystal structure. A Zn-NO3- battery cathode also shows record-high performance.
Ambient electrochemical nitrite (NO2-) reduction is viewed as an effective and sustainable approach for simultaneously removing NO2- producing ammonia (NH3).
