A novel ammonia synthesis catalyst, potassium-promoted ruthenium supported on carbon nanotubes, was developed. It was found that the Ru-K/carbon nanotubes catalyst had higher activity for ammonia synthesis (20.85 ml NH₃/h/g-cat) than the Ru-K/fullerenes (13.3 ml NH₃/h/g-cat) at atmospheric pressure and 623 K. The catalyst had activity even at 473 K. and had the highest activity (23.46 ml NH₃/h/g-cat) at 643 K. It was suggested that the multi-walled structure favored the electron transfer the hydrogen-storage and the hydrogen-spill which were favorable to ammonia synthesis.
