以松香基季铵盐为模板剂合成介孔γ-Al2O3
Synthesis of Mesoporous γ-Al2O3 Using Rosin-based Quaternary Ammonium Salt as Template Agent
摘要
Abstract
Aluminas with uniform mesoporous structure was synthesized using rosin-based quaternary ammonium salt as a template agent,and its structure was characterized with X-ray diffraction,transmission electron microscopy and N2 adsorption and desorption.The results indicated that the surface area and pore diameter of the mesoporous γ-Al2O3 calcinated at 650℃ were in the range of 194 -213 m2/g and 4.18 -5.18 nm respectively.The content of the rosin-based quaternary ammonium salt had significant influence on the textural properties of mesoporous γ-Al2O3.The addition of suitable amount of rosinbased quaternary ammonium salt endowed mesoporous γ-Al2O3 with large pore diameter and narrow pore distribution.关键词
