Ultrasound-assisted reconstruction and delamination studies on CaAl layered double hydroxides
Source abstract
Abstract
Abstract Two kinds of CaAl layered double hydroxides (CaAl-LDHs) were synthesized with chloride and nitrate anions by co-precipitation method. The samples were calcined and finally reconstructed by rehydration using ultrasounds, in the presence of NaCl or NaNO 3 . Reconstructed samples presented smaller lamella size than the parent ones. All samples were characterized by X-ray powder diffraction, FT-IR spectroscopy, thermogravimetric analysis and TEM microscopy. Delamination was not achieved by mechanical stirring for 2 days, whereas most samples underwent delamination by the use of ultrasounds. Additionally, a hybrid CaAl-LDHs with CdTe quantum dots was synthesized by reconstruction of a calcined CaAl-LDHs in the presence of the quantum dots.
