Methanol synthesis from CO2 hydrogenation over Cu/γ-Al2O3 catalysts modified by ZnO, ZrO2 and MgO

- Modification of metallic oxides improves Cu dispersion of Cu-supported catalysts.
- Activation temperature can affect Cu dispersion.
- Methanol formation easily occurs on the small Cu0 particles.
- High reaction temperature will inhibit methanol synthesis.
