Paper Title
Effects Of Hydrolysis Degree On The Titanium Dioxide Photocatalyst Powder Via Sol-Gel Method

Abstract
-In this paper, nanosized TiO2 powder with anatase structure has been synthesized via sol-gel method using titanium tetraisopropoxide as a precursor and their physicochemical properties were studies. The mole ratio of titanium tetraisopropoxide (i.e. 0.2mol) mixed with 50 ml methanol to evaluate effect of hydrolysis degree. The synthesized powders were characterized by XRD, TG-DTA, FT-IR and SEM. The average particle sized of TiO2 is calculated from XRD and found to be 83.538 nm (i.e. ~83 nm). The DTA analysis shows that amorphous phase transform into anatase phase at lower temperature (below 4000 c.) TGA analysis exhibit that there is removal of unhydrolysed isopropoxide bonded in TiO2 due to weight loss. FT-IR analysis indicates that the inorganic bond of Ti-O does not exist at low wave number. The morphological study carried by SEM shows TiO2 powder consist of spherical shaped particles. Keywords- Nanostructured TiO2, sol-gel, photo- catalysis, anatase, morphologica
