摘要

Abstract

A polyaluminium chloride solution with high Al

content self-prepared was used as material for preparing the spherical γ-Al

by the sol-gel and oil-drop method. Polyethylene glycol with different molecular mass was used as surfactant to investigate the effect on property of γ-Al

. The physical property was characterized by

Al NMR (nuclear magnetic resonance) spectra

X-ray diffraction

FT-IR (Fourier transform infrared spectroscopy) and TG-DTA (thermogravimetric-differential thermal analysis). The results showed that surface area

pore volume and pore size of γ-Al

all increased with the increase of polyethylene glycol molecular mass in the experimental research range

and polyethylene glycol 10000 was the most suitable pore forming additive. γ-Al

with surface area of 339 m

·g

-1

pore volume of 0.59 cm

·g

-1

and pore diameter of 6.9 nm were obtained at 450℃.
