摘要：

Nonthermal plasma (NTP) provides a potential and sustainable route for the synthesis of ammonia. In this work, a Co-Ni/MOF-74 catalyst was developed to synthesize ammonia from N-2 and H-2 in a dielectric barrier discharge (DBD) plasma at low temperature and atmospheric pressure. Co-Ni/MOF-74 showed the highest ammonia synthesis rate up to 2608.70 mu mol g(-1) h(-1) at 200 degrees C, with V(N-2):V(H-2) ratio of 1:1 and specific energy input of 33.27 kJ L-1. The catalytic activity was increased by 19.57% for Co-Ni/MCM-41 and 375% for Co-Ni/Al2O3, respectively. It was observed that the average electric field (E) and power efficiency were enhanced while adding Co-Ni/MOF-74 to the reaction system.
