This paper summarizes some of our recent research work on the synthesis of nanofluids (dilute liquid suspensions of nanoparticles). In the present work, Tio2 Nano particles have been synthesized by Sol-gel technique. The Prepared powders were characterized by using XRD, SEM. The Crystalline size of TiO2 powder was found to ~6 nm for anatase at 400 ºC by controlling the acidity. TiO2 water nanofluids with different volume concentrations from 1% to 2% were then prepared by dispersing the synthesized Nano particles in deionised water.
