2026-09-20 Cerium modification of the MnOx–Na₂WO₄ system promotes the co-conversion of methane and carbon dioxide. doi:10.57760/sciencedb.45655 en This dataset contains the experimental data associated with the development of CeO₂-modified MnOx–Na₂WO₄/SiO₂ oxygen carriers for CO₂-assisted chemical looping oxidative coupling of methane (CO₂-CLOCM). The dataset includes catalyst preparation information, catalytic performance data, cyclic stability tests, and physicochemical characterization results used to elucidate the role of CeO₂ in regulating oxygen transfer behavior. The catalytic data include CH₄ conversion, CO₂ conversion, C₂⁺ product selectivity, and C₂⁺ production rate under different Ce contents and reaction conditions. Characterization datasets include XRD, TEM, N₂ adsorption–desorption, CO₂-TPD, H₂-TPR, O 1s XPS, in situ Raman, in situ FTIR, and isotope-labeling mass spectrometry results. These data provide insights into the relationship between CeO₂ incorporation, lattice oxygen regulation, oxygen exchange behavior, and selective methane conversion. The dataset is intended to support reproducibility of the reported results and facilitate further development of oxygen carriers for sustainable methane valorization and CO₂ utilization.
