Plasma-assisted catalysis for ammonia synthesis in a dielectric barrier discharge reactor: key surface reaction steps and potential causes of low energy yield

Zhe Chen et al.

Summary: Ammonia synthesis experiments were carried out in a coaxial dielectric barrier discharge (DBD) reactor packed with various supports and metal catalysts. The addition of packed bed particles led to a significant increase in the reaction rate. Kinetic analysis revealed that ammonia synthesis mainly proceeds by the adsorption of reactive radicals in the gas phase and subsequent reactions on metal and support material surfaces.

Identifying Regimes During Plasma Catalytic Ammonia Synthesis

Sophia Gershman et al.

Summary: In this study, the performance of mesoporous silica SBA-15 and SBA-15-Ag in plasma ammonia synthesis was investigated. It was found that the performance of SBA-15 and SBA-15-Ag reactors varied under different plasma conditions. Optical emission spectroscopy was used to analyze the plasma conditions, and the electron density and nitrogen decomposition parameters were measured. The results showed that SBA-15 reactors had higher electron density and N-2 vibrational temperature, while the addition of Ag resulted in higher N-2 rotational temperature. Furthermore, SBA-15 exhibited better stability and surface area retention after plasma exposure.

Shielding Protection by Mesoporous Catalysts for Improving Plasma-Catalytic Ambient Ammonia Synthesis

Yaolin Wang et al.

Summary: Plasma catalysis holds promise for decentralized NH3 synthesis using renewable energy, with a bespoke design of supported Ni catalysts showing potential for efficient NH3 production. By depositing Ni active sites on the surface of mesoporous MCM-41, it enhances plasma-catalyst interactions and shields NH3 from decomposition, driving the reaction forward effectively. This demonstrates the importance of rational catalyst design for improving plasma-catalytic processes.
