Plasma-Enabled CO2/CH4 Conversion into Li Quid Chemicals: Effect of Valence States and Microstructure of the Catalysts

At present, the one-step conversion of greenhouse gas into value-added liquid chemicals with a considerable selectivity is one of the biggest technical challenges to us 1 . Integrating non-thermal plasma (NTP) technology with heterogeneous catalyst is a promising way to tackle this challenge 2 , mainly owning to its strong synergy effect and high efficiency in overcoming the thermodynamic limitation of reactions. In this paper, NTP driven by nanosecond pulse power source, has been utilized for direct CO 2 /CH 4 conversion in a dielectric barrier discharge reactor. This work mainly focuses on revealing the relations between the valence states, surface compositions and defect structures of varied catalytic models on conversion performance and liquid oxygenates distribution.
