Synthesis and Surface Modification of a Rod Shaped Nanometer g-Al2O3

Abstract

A simple co-precipitation method was adopted to synthesize nanometer  g-Al₂O₃ and then surface modification was implemented by coupling agent KH-550. The structure and morphology of the modified and unmodified g-Al₂O₃ were characterized by XRD, IR and TEM. The results show that the particles were 30 nm rod shape and homodisperse. The lipophilic groups were endowed onto the surface of modified g-Al₂O₃.
