Synthesis and characterizations of CoTiO۳-clay nanocomposites by sol-gel method

CoTiO۳-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at ۵۰۰ - ۸۰۰°C for ۲ hours. The presence of rhombohedra phase of CoTiO۳ in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with ۵-۲۰%(w/w) by sol-gel method. The spectra results were investigated at ۲۰% (w/w) concentration .The optimum condition for nano-composite preparation in ۲۰ %( w/w) at ۶۰۰°C is obtained.
