Structural, Morphological and Antibacterial Activity of Kaolinite/TiO2 Nanocomposites
P. Mariselvi, G. Alagumuthu*

The development of rapid and reliable processes for the synthesis of nanomaterial is of great importance in the field of nanotechnology. In this paper, the synthesis of kaolinite/TiO2 nanocomposite was carried out by using solvothermal method. The obtained nanocomposite was characterized by using XRD, SEM, TEM and UV-Vis absorption spectroscopy. The XRD pattern reveals that in the course of composites formation, kaolinite/TiO2 nanocomposites containing the anatase phase of TiO2 were found. The spherical morphology of kaolinite/TiO2 nanocomposites were observed in SEM and TEM analysis. The UV absorption edges exhibited a blue shift, which might be caused by nanosize effect. The nanocomposites size can be calculated from Debye-Scherrer’s formula. The antibacterial assay of synthesized nanocomposites was studied with the three bacterial pathogens viz., Staphylococcus aureus, E. coli and Micrococcus luteus.
