Synthesis of texture-excellent mesoporous alumina using PEG1000 as structure-directing agent
摘要
Abstract
By varying concentration of PEG1000 as a structure-directing agent
mesoporous alumina with excellent textural properties was synthesized. The prepared mesoporous alumina displays high thermal stability
as shown by its textural properties at different calcination temperatures of 600-850℃. Characterization by SEM and TEM revealed that the added PEG surfactant induced the formation of petal-like alumina. XRD results clarified that all samples were amorphous and their peaks were around the peaks of

adsorption-desorption analysis showed that the prepared mesoporous alumina
if with PEG1000 in hydrolysis of aluminum isopropoxide
had excellent textural properties with large specific surface area
high pore volume and suitable pore size. The petal-like structure existing in the alumina samples improved their textural parameters
and the role and influential mechanism of PEG1000 were analyzed.
