Gallium Cathode Boosts Efficiency in Lab Ammonia Synthesis
Original: A gallium-based cathode changed how lithium activates nitrogen in laboratory ammonia synthesis. The team reported 96 ± 6
Researchers have reported that a gallium-based cathode changes how lithium mediates nitrogen activation in laboratory-scale ammonia synthesis. The team measured a faradaic efficiency of 96 ± 6% and estimated energy efficiency of at least 22%, figures that draw attention in a field where electrochemical ammonia production has long struggled with poor efficiency. However, the work remains at laboratory scale: no scaled, durable electrolyser has been demonstrated, and it is unclear whether the approach could compete with the established Haber-Bosch process for real-world fertilizer production.
Why now: The reported efficiency figures are notable for electrochemical ammonia synthesis, a long-sought alternative to the energy-intensive Haber-Bosch process.
