Sulfur vacancy-rich N-doped MoS2 nanoflowers act as highly effective electrochemical catalysts for efficient nitrogen reduction.

Hollow Ni–Fe@MoS2 NCs were designed and studied for N2 reduction to NH3. Their high performance could be attributed to the unique structure with abundant Ni–Fe active sites.

Electrochemical C–N coupling reaction by renewable electricity for the electrosynthesis of organonitrogen compounds with the abundant CO2 and nitrogenous small molecules as carbon and nitrogen sources, respectively, is a promising sustainable synthetic strategy.
