Abstract

Binary Cu/ZnO catalysts were prepared by solid-state method and tested for vapor-phase low-temperature methanol synthesis from CO₂-containing syngas. The influence of H₂C₂O₄/(Cu + Zn) molar ratio on the physicochemical properties and the corresponding catalytic activity was systematically studied. The space time yield (STY) of methanol exhibited a linear relationship with the Cu⁰ surface area, and increased linearly by enhancing the number of strongly acidic sites or moderately basic sites. The effects of various parameters on the methanol synthesis reaction were also investigated. C_4-Red catalyst (H₂C₂O₄/(Cu + Zn) = 4/1) exhibited the maximum turnover frequency (TOF, 11.4 × 10⁻³ s⁻¹) and STY values (456.3 g/kg h⁻¹), due to the larger Cu⁰ surface area, greater specific surface area, more strongly acidic sites and moderately basic sites. The strengthened Cu-ZnO interaction, superior CO and H₂ adsorption capability as well as higher adsorbed CO and H₂ amount also contributed to increasing the catalytic performance of C_4-Red catalyst.
