Titania (TiO2) nanoparticles were prepared by combining bulk titania with trisodium citrate solution at room temperature without calcination. The formation of titania nanoparticles was confirmed from XRD and by the dominant FTIR peaks at 621 cm-1, 412 cm-1. UV-Visible analysis shows the occurrence of strong red shift, confirming the presence of nanoparticles which is essential for higher photo catalytic activities. TGA analysis reveals that the synthesized titania nanoparticles were thermally stable up to 700 0C. SEM image shows that the particles of the synthesized sample are in nanometer range which is in accordance with UV-Visible studies.
