Abstract
ZnAl Layered Double Hydroxides with nitrate as interlamellar anion have been synthesized in the presence of different amines [methylamine (MMA), dimethylamine (DMA) and trimethylamine (TMA)] in the coprecipitation medium. Then, the solids were submitted to hydrothermal post-treatment by conventional heating and microwave assisted heating in order to improve the crystallinity and the properties of the solids. The samples were characterized by element chemical analysis, powder X-ray diffraction, FT-IR spectroscopy, thermal analysis, specific surface area analysis, SEM, and particle size distribution. The results showed an enhancement of their crystallinity when the samples had been synthetized in the presence of DMA, such a crystallinity degree improving after a long hydrothermal treatment. Although aggregates were formed, they disaggregated easily after short ultrasound treatments, and thus it was possible to obtain solid with a narrow particle size distribution.
