Microporous Structure of Alumina Prepared by a Salt Catalytic Sol-Gel Process

A microporous structure of alumina with a narrow distribution of the pore size (∼0.4 nm in diameter) was synthesized by a salt catalytic sol-gel process of dilute Al(OCH(CH3)2)3 and H2O solution without any template molecule. The specific surface area of alumina after the calcination at 300 °C was 9...

Description
Summary:A microporous structure of alumina with a narrow distribution of the pore size (∼0.4 nm in diameter) was synthesized by a salt catalytic sol-gel process of dilute Al(OCH(CH3)2)3 and H2O solution without any template molecule. The specific surface area of alumina after the calcination at 300 °C was 960 m2g-1 while it was 170 m2g-1 even after the calcination at 900 °C.
