Metal oxide nano-composites plays a very important role in many areas of chemistry, physics and material science. This paper explains the synthesis and comparison of zinc and zirconium doped TiO₂ metal oxide nano-composites and their different properties. Here the sol-gel method is used to synthesis both the nano-composites. Nano-composites have been characterized with XRD, AFM, Zetasizer & potential and FT-IR studies. XRD study revealed good crystallinity with the size range of 30 nm – 45 nm for both nano-composites. AFM studies also revealed the same. FTIR study reports the characteristics peaks of synthesised nano-composites.
