Abstract

CoTiO3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 – 800°C for 2 hours. The presence of rhombohedra phase of CoTiO3 in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. The spectra results were investigated at 20% (w/w) concentration .The optimum condition for nano-composite preparation in 20 %( w/w) at 600°C is obtained.
