| Abstract: The nano γ-Al2O3 was prepared by chemical precipitation combined with supercritical CO2 drying. The nano γ-Al2O3 was characterized by TG-DTA analysis, XRD diffraction, N2 physical adsorption-desorption testing, SEM and TEM analysis. Compared with the sample prepared by general drying, smaller particle size and greater surface area were obtained. The supercritical CO2 drying was more effective in reducing aggregation. |
