Abstract

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%. 15NH3 isotope tracing and optical emission spectroscopy show that gas-phase active species (NH3*, NH˙) in the plasma zone facilitate the desorption step by an Eley–Rideal (E–R) interaction.
