Summary: It has long been believed that FeMoS structure plays a crucial role in electrochemical nitrogen fixation, but the structure of Fe bonded with heavier analogues (Se or Te) has never been explored. However, this study, based on theoretical predictions, discovers that the FeMo(Se, Te) structure, with Fe bonded to Se, exhibits enhanced N-2 electrofixation activities. Further mechanism studies provide new clues for designing versatile electrocatalytic materials for large-scale industrialization.

Summary: Ammonia (NH3) is a globally important commodity for fertilizer production, but its synthesis by the Haber-Bosch process causes substantial emissions of carbon dioxide. Alternative methods being explored include the promising electrochemical lithium-mediated nitrogen reduction reaction, which has required sacrificial sources of protons. In this study, a phosphonium salt is introduced as a proton shuttle to help resolve this limitation, resulting in high NH3 production rates and demonstrated continuous operation for more than 3 days.
