Synthesis of Uniform Mesoporous γ-Al2O3 Using Rosin-based Quaternary Ammonium Salt as a Directing Agent
Aluminas with uniform mesoporous structures were synthesized using rosin-based quaternary ammonium salt as a directing agent for the first time, and their structures were characterized with X-ray diffraction and N2 adsorption and desorption. It was indicated from the test results that the surface areas and pore diameters of the mesoporous γ-Al2O3 calcinated at 650 ℃ were in the range of 194 ～213 m2g-1 and 4.18～5.18 nm, respectively, and the content of the rosin-based quaternary amonium salt gave significant influence on the textural properties of the aliminas.The addition of suitable amount of rosin-based quaternary ammonium salt endowed the aluminas with large pore diameter and narrow pore distribution.
