WOx Nanoparticles Coupled with Nitrogen-doped Porous Carbon toward Electrocatalytic N2 Reduction

WO x nanoparticles coupled with nitrogen-doped porous carbon (WO x /NPC) via W–N bonding were prepared via one-step thermal pyrolysis. WO x /NPC could deliver a high NH 3 yield of 46.8 μg h −1 mg −1 and a high faradaic efficiency (FE) of 10.2%.
