Strongly adsorbed N atoms inhibit the ammonia decomposition reaction rate. Plasma-driven catalysis can solve this problem and increase the ammonia conversion from 7.8% to 99.9%. (NH3)-N-15 isotope tracing and optical emission spectroscopy show that gas-phase active species (NH3*, NH center dot) in the plasma zone facilitate the desorption step by an Eley-Rideal (E-R) interaction.
