Plasma-enhanced catalytic ammonia synthesis
Ammonia may be one of the energy carriers for the hydrogen economy. However, the activation of dinitrogen is difficult and the conventional ammonia synthesis occurs high temperatures and high pressures (400-500°C and 100-450 bar). Therefore, alternative technologies are studied, especially for small-scale, on-demand applications.
Plasma-enhanced catalysis is an emerging technology to overcome scaling relations in heterogeneous catalysis. The bond in dinitrogen can be activated by a plasma, allowing for milder ammonia synthesis conditions. However, plasma-catalyst interactions are complex and not well understood. In the current study, plasma-enhanced catalytic ammonia synthesis is studied from the catalysis perspective.
