ZnO/TiO2 Nanocomposites Semiconductor for Anti-Bacterial Applications and Dye Sensitized Solar Cell applications
The synthesis of high quality ZnO doped TiO2 nanoplatelets were synthesized by hydrothermal method at room temperature (RT). Composition, structure and micro morphology of the nanoplatelets were analyzed and determined by X-ray diffraction (XRD) confirms that crystal structure of doped (Zn-Ti-O) composition the identify peaks of (002), (100) and (101) clearly showed hexagonal wurtzite-type structure of ZnO with same lattice constants of the same; a=b=3.249 Å and c= 5.219 Å. From the XRD results revealed that crystal properties of the doped samples are improved without affecting the parent lattice. The morphological and optical properties of Zn-Ti-O nanosamples were characterized by scanning eelectron microscopy (SEM). TEM observation shows that the ZnO/TiO2 nanoplatelets synthesized by hydrothermal synthesis are well dispersed and the average crystallite size was found to be 10 nm. Biological applications of bacterial strains were calculated for these samples. The antibacterial activity of ZnO/TiO2 and its doping was evaluated on bacteria strains like Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The results obtained in this study suggested that the ZnO/TiO2 and its doping have potential for use in the treatment of diseases caused by these test organisms.
