Abstract: Au and Pt doped TiO2 nanocrystlas were prepared using the sol gel method. Diffuse Reflectance Spectroscopy (DRS) was used to study the characteristics of these precious metals and X-ray diffraction (XRD) with calculated lattice parameters was used to study the location of these precious metal dopants in nanocrystalline TiO2. The effects of these dopants on the phase transformation and grain growth were observed. Electron Microscopy was used to study the morphology. The results of the lattice parameter calculations from the XRD patterns of metal loaded TiO2 are almost the same as for the undoped.
