摘要
This preliminary study focuses on the ability of organic compounds such as polyols to tune size and morphology of boehmite nanoparticles by aluminium precipitation in aqueous medium. Results show a notable effect of both the synthesis pH and the carbon chain length of polyols, ie C4 and C5, on the size of particles and their thickness to width ratio. The specific surface area can be increased up to 382 m(2).g(-1). In addition, the morphology of particles is modified by C5 polyol.
