Improving the energy yield of plasma-based NOx synthesis with in situ adsorption

Abstract

Plasma-based NO_x synthesis from air is a promising option to electrify nitrogen fixation. However, the energy efficiency of direct plasma-based NO_x synthesis in a plasma reactor is severely limited by NO_x decomposition in the plasma phase. In situ NO_x adsorption on MgO improves the NO_x energy yield in a dielectric barrier discharge (DBD) plasma reactor by a factor of 15.
