| 摘 要： | Ni-Al-CO3LDHs/γ-Al2O3have been prepared using an in-situ synthesis technique. NH3·H2O was chosen as activation agent of Al on the γ-Al2O3surface as well as precipitant. Ni-Al-CO3LDHs/γ-Al2O3was synthesized by controlling the reaction conditions such as temperature, concentration of Ni2+ and initial pH. The crystalline structure, chemical composition and porous structure were characterized by means of XRD, FT-IR, TG-DTA, 27Al MAS-NMR and N2 adsorption-desorption. The resulting sample of Ni-Al-CO3LDHs/γ-Al2O3possesses higher specific area and narrower pore distribution, in which Ni-Al-CO3LDHs are located on the surface of γ-Al2O3and share the same Al-O bonds with the γ-Al2O3lattice. Finally a possible structural model was proposed to account for the porous characters of Ni-Al-CO3LDHs/γ-Al2O3.
