英文摘要Ammonia is synthesized directly from water and N-2 at room temperature and atmospheric pressure in a flow electrochemical cell operating in gas phase (half-cell for the NH3 synthesis). Iron supported on carbon nanotubes (CNTs) was used as the electrocatalyst in this half-cell. A rate of ammonia formation of 2.2 X 10 (-3) g(NH3) m (-2) h (- 1) was obtained at room temperature and atmospheric pressure in a flow of N-2, with stable behavior for at least 60h of reaction, under an applied potential of - 2.0 V. This value is higher than the rate of ammonia formation obtained using noble metals (Ru/C) under comparable reaction conditions. Furthermore, hydrogen gas with a total Faraday efficiency as high as 95.1% was obtained. Data also indicate that the active sites in NH3 electrocatalytic synthesis may be associated to specific carbon sites formed at the interface between iron particles and CNT and able to activate N-2, making it more reactive towards hydrogenation.
