dc.description.abstract | The influence of different metal oxides (ZnO, ZrO2, In2O3) in CO2 hydrogenation to methanol over Cu-based catalysts was studied. The catalysts were characterized using x-ray diffraction (XRD), thermal gravimetric analysis (TGA), transmission electron microscopy (TEM), N2-physisorption, N2O chemisorption, H2 temperature-programmed reduction (H2-TPR), and CO2 temperature-programmed desorption (CO2-TPD). It was found that impregnating ZrO2 onto Cu/ZnO enhances the methanol formation rate from 14.7 mmol∙gcat−1∙h−1 to 15.6 mmol∙gcat−1∙h−1 (230 °C, 30 bar, 38 000 cm3/(gcat h)), which is attributed to the formation of Cu-ZrO2 sites. The results also indicate that In-doping of the Cu-based catalysts generates CuxIny alloys, which seems to inhibit the active sites on the Cu surface. However, new sites for methanol synthesis are present when Cu/ZrO2/In2O3 is prepared by co-precipitation. This is attributed to In-Zr mixed oxide species that increases the methanol formation rate from 53.2 mmol∙gcat−1∙h−1 to 60.5 mmol∙gcat−1∙h−1 (270 °C, 30 bar, 140 000 cm3/(gcat h)). | en_US |
