Exploring the feasibility of liquid fuel synthesis from CO₂ under cold plasma discharge: role of plasma discharge in binary metal oxide surface modification.

ABSTRACT: The conversion of CO₂ to CH₃OH over binary mixed metal oxides of NiO-Fe₂O₃ is investigated in the study. A series of catalysts, i.e., NiO, Fe₂O₃, 5% NiO-Fe₂O₃ (5NF), 10% NiO-Fe₂O₃ (10NF), and 15% NiO-Fe₂O₃ (15NF), was tested for CO₂ conversion and CH₃OH selectivity performance. The results show that binary mixed metal oxides are more active in comparison to pure metal oxides. Moreover, increasing NiO mixing leads to the agglomeration of NiO particles. At 200 °C, around 1.5%, 2%, and 3.2% CO₂ conversion is achieved for 5NF, 10NF, and 15NF, respectively. Interestingly, when cold plasma was ignited at 200 °C, around 5.4%, 6
