Abstract
TiO_2 nanoparticles have been synthesized using titanium (IV) isopropoxide. SEM imaging revealed that TiO_2 nanoparticles with an average diameter of 15 nm. The physicochemical properties of TiO_2 film papered by a spin coating on a glass slide were determined. A thickness of film was estimated by SEM. The reflective index of TiO_2 coating was determined by simulation method. The TiO_2 was applied to modify electrode and exhibited catalytic activity for chlorophenol, 2-chlorophenol, and 4-nitrophenol, as three test models.The detection limits was 1μM with linearity up to 10μM.
