Abstract: 

Nanocrystalline TiO2 sample has been synthesized by using Titanium (IV) isopropoxide and sodium sulfate as precursors via an simplistic route called sol-gel synthesis at 500C temperatures. The synthesized products were characterized by XRD, Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM/EDS), transmission electron microscopy (TEM), UV-Visible spectroscopy (UV-Vis) and Photoluminescence spectroscopy (PL). The sulfur concentration increased the crystallization of TiO2 from anatase to rutile. The analysis confirmed that the TiO2 nano crystals are below 30 nm. The presence of functional groups and chemical bonding is confirmed by FTIR. The morphology of TiO2 powders was of irregular shape nanoparticles with various caves, which mainly resulted from the agglomeration of nanocrystaline TiO2. The PL performed the UV emission peak in a range of 430-470 nm with red shift.
