Bio activity testing of SnO2-TiO2 nanocomposite synthesis by chemical methods

In this work, SnO2:TiO2 nano composite with silver dopant have been prepared by chemical route method at preparation temperature 100 ℃ , with 6% Ag ratio. Titanium chloride (TiCl3) has been used as the precursors of TiO2 and tin chloride (SnCl2) were taken as the precursors of SnO2 in the laboratory. The prepared samples were described by FESEM, X-Ray diffraction and uv-visible spectrophotometer. Results show that compared to pure SnO2 and pure TiO2 ,SnO2:TiO2 nano composite calcined 400℃ shows a large surface area. The average crystalline size was estimated from XRD analysis by using Debye-Scherrer’s formula and the result shows that the crystalline size increases from (27.78) nm to (29.2354)nm after adding Ag. Bio activity application of the prepared composite has been tested after immersion SnO2:TiO2 nano composite in the simulated body fluid SBF, the morphology and particle size of the prepared immersed samples have been estimated after 20 days by FESEM images.
