Preparation of Nano activated γ-alumina (Al2o3 )‎ with surfactant and surface characterization

Abstract EN

This paper deals with the preparation of Alumina by sol-gel technique through the hydrolysis of aluminum ion mixed with the glucose as a surfactant and converting it to gel by ammonium hydroxide in aqueous media.

The resulting sol composed of particle is draying to become a transparent gel.

The freshly prepared gel is heated at 700°C for 2hrs to obtain alumina ( )particles.

The obtained particles are found to be γ-alumina particles with high porosity, Their characteristics are determined by LPSA, XRD, SEM, TEM and BET techniques.

The results show that the particles are pure alumina, nano-sized=20nm, spherical shape, high surface area=210 /gm.
