| 摘 要： | 对传统共沉淀法进行改进,在老化阶段通入CO2促进母液中前驱体物相的转变,制备了Cu/ZnO/Al2O3催化剂.N2吸附、X 射线衍射、场发射扫描电子显微镜、程序升温还原、程序升温分解结果表明,改进共沉淀法制备的催化剂前驱体中碱式硝酸铜更易转变为碱式碳酸铜,从而提高了前驱体的稳定性,并使得焙烧后的催化剂具有较大的比表面积...

| Abstract: | A Cu/ZnO/Al2O3 catalyst prepared by adding CO2 during the aging step was used for methanol synthesis from CO2 and H2. The catalysts were characterized by N2 adsorption-desorption, X-ray diffraction, field emission scanning electron microscope, temperature-programmed decomposition, and temperature-programmed reduction. The precursor from the modified method with added CO2 had malachite and hydrotalcite-like phases and was more stable than that of the sample without added CO2. After calcination, the modified ... |
