摘要：以松香基季铵盐为结构导向剂制备均匀介孔氧化铝,采用XRD,N2-吸附脱附和TEM表征样品的结构性能。结果表明:经过650℃焙烧,所得样品为介孔γ-Al2O3,比表面积为194～213 m2/g,平均孔径为4.18～5.18 nm。松香基季铵盐的添加量对氧化铝的结构性能有着较大的影响,适量添加松香基季铵盐有利于氧化铝获得较大的孔径和较窄的孔径分布。
Aluminas with uniform mesoporous structure was synthesized using rosin-based quaternary ammo-nium salt as a template agent,and its structure was characterized with X-ray diffraction,transmission electron microscopy and N 2 adsorption and desorption.The results indicated that the surface area and pore diameter of the mesoporous γ-Al 2 O 3 calcinated at 650℃ were in the range of 194-213 m^ 2 / g and 4.18-5.18 nm respectively.The content of the rosin-based quaternary ammo-nium salt had significant influence on the textural properties of mesoporous γ-Al 2 O 3.The addition of suitable amount of rosin-based quaternary ammonium salt endowed mesoporous γ-Al 2 O 3 with large pore diameter and narrow pore distribution.
