Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.
