The comparison of preparation method is shown in the present work. TiO₂/ZrO₂ Nanocomposite was synthesized by two different precipitation and hydrothermal method. The structural properties of the prepared samples were analyzed by X-ray diffraction spectroscopy. The average crystallite sizes were calculated by Scherrer formula. From the XRD it was confirmed that the TiO₂ exists in two different phases Anatase and Rutile whereas ZrO₂ exists in two different phases monoclinic and tetragonal. The surface morphology was studied by Scanning Electron Microscopy. The optical absorption was measured by UV-Visible spectroscopy. The absorption spectra were taken in the wavelength range 200-900 nm. The optical band gap was calculated by establishing relation between $(\alpha h\nu)^2$ and $h\nu$. All other optical constants such as refractive index, extinction coefficient, absorption coefficient and optical conductivity were calculated from absorption spectra.
