Characterization of Titanium Oxide Nanoparticles Obtained by Hydrolysis Reaction of Ethylene Glycol Solution of Alkoxide
Figure 4
UV-VIS absorption spectra of the sols obtained by heating the mixture of ethylene glycol solution of TIP and NH3 (aq) at 368 K for 24 h. The solid line shows the spectra of the obtained sols. The NH3 (aq) concentrations were (a) 0.05 mol/L, (b) 0.1 mol/L, (c) 0.2 mol/L, (d) 0.5 mol/L, and (e) 1 mol/L. The broken lines show spectra of the isopropanol solution of TIP. The TIP concentrations of the solutions were (f) 1 mol/L, (g) 0.1 mol/L, and (h) 0.01 mol/L.
