ABSTRACT

An organic-inorganic nanohybrid material of zinc-aluminium-layered double hydroxide

containing beta-naphtoxyacetic acid (BNOA) as the interlamella anion was synthesized

using co-prepitation method. BNOA ion was successfully intercalated into Zn-Allayered

double hydroxide by expanding the interlayer spacing from 8.93 to 19.46

based on the PXRD diffractogram of the nanocomposite. Thermal composition

(calcination) of the nanocomposite (Zn-Al-BNOA) was studied by heating the samples

at 100 800 C under atmospheric condition. The layered structure of the

nanocomposite collapsed when the sample was heated at 350 C and the formation of

ZnO phase was observed at 400 C and higher. Further characterization for the FTIR

and organic-inorganic composition and SEM, were also carried out.
