we demonstrate the synthesis of ammonia via atmospheric
dielectric barrier discharge (DBD) plasma discharge over zeolite 5A.
The presence of the zeolite in the DBD reactor promoted the formation
of microdischarges and a change of the voltage–current characteristics
of the reactor, leading to an enhanced catalytic performance. The
perturbation of the zeolite surface electronic properties due to atmospheric
plasma led to an enhanced reactive state at the zeolite surface
which promoted the dissociation of nitrogen and the subsequent formation
of ammonia. An energy yield of 15.5 g-NH3/kW h was observed
at an equimolar N2 to H2 ratio in the presence
of zeolite 5A, which is at least 50 times higher than that obtained
in the absence of the zeolite.
