Insight into the impacts of MnO2 crystal phases on CO2 selective hydrogenation to CH4 on Ni/MnOx catalysts
Ni-based catalysts using ε-, α- and β-MnO2 crystal phases supports were prepared and applied to CO2 hydrogenation. The samples were characterized by XRD, H2-TPR, BET, SEM, (HR)TEM, CO2-TPD, Raman, quasi in situ XPS, and in situ DRIFTS. Ni/MnOx-NS (ε-MnO2) was found to exhibit stable activity (with 6...
