Synthesis an d charac terization of y-alum ina porou s nanopa rticles from Sodium alu minat liquor with two type surfactants

In recent years, nanomaterials have received considerable attention because of their s pecial struct ures and fun ctions whic h are different from tr aditional ma terials [۱]. The Ȗ-alumina is one kind of extremely important nanosi zed materials [۲]. In this article, w e report a novel proces sing method for synthesize Ȗ-Al۲O۳ nanopartic les by two type surfactants as structure-directing agents. The aim of this stud y is the sy nthesis of n anoparticles with very fine crystallite size, lo w cost, high synthesis ra te and also investigates two type su rfactants in order to nanoparticles s ynthesis of Ȗ-alumina with used sodi um aluminat liquor.Mate rials and m ethods:Sodiu m aluminat liquor, HCl (۳۷%, Merck), NaOH (Merck), Po lyvinyl alc ohol (Merck) and Polyethylene glycol (۲۰۰۰-۴ ۰۰۰, Merck) were used as raw materials to prepare na no-y-alumin a. Among the various synthesis methods, we used sol-gel method for synthe sis of nanop articles.
