abstract = {This study demonstrates the reduction of carbon dioxide (CO2) via a plasma-catalyst hybrid process in the presence of methane (CH4) and hydrogen (H2). Dielectric barrier discharge (DBD) plasma-activated Ar/CO2/CH4/H2 was applied to copper nanoparticles supported on zinc oxide (ZnO). The surface species and their reaction pathways were investigated via in situ Raman spectroscopy under DBD irradiation. The Raman shift peaks were identified from literature review and density functional theory (DFT) calculations. Acetate (CH3COO) was produced as the reaction product via a DBD -induced surface reaction. In addition, acetaldehyde (CH3CHO) was produced by irradiation with DBD -activated H2O. The conversion of CO2 and CH4 to valuable compounds was evaluated via in situ observations, and the reaction pathway was examined.},
