以硝酸镍和正硅酸乙酯为原料采用溶胶凝胶超临界流体干燥法制备了不同镍含量的气凝胶催化剂。XRD ,TPR ,TEM ,IR等物理技术表征和顺酐液相催化加氢活性评价结果表明 :NiO/SiO2 气凝胶催化剂中NiO与SiO2有较强的相互作用 ,镍含量对活性组分与载体之间相互作用的影响导致催化剂具有不同的丁二酸酐和γ 丁内酯的选择性。在镍含量为 30w % ,经 6 73K焙烧的催化剂上γ 丁内酯的选择性最佳 Aerogels catalysts with different nickel contents were prepared by sol-gel supercritical fluid drying using nickel nitrate and tetraethyl orthosilicate as raw materials. Physical and chemical characterization of XRD, TPR, TEM, IR and other liquid phase catalytic hydrogenation activity evaluation results show that: NiO / SiO2 airgel catalyst NiO and SiO2 have a strong interaction, the nickel content of the active component and carrier The effect of the interaction results in the catalyst having different selectivity to succinic anhydride and gamma butyrolactone. Γ-butyrolactone is the most selective catalyst with a nickel content of 30w% and calcined at 673K
