Characterization of Titanium Oxide Nanoparticles Obtained by Hydrolysis Reaction of Ethylene Glycol Solution of Alkoxide

Table 1

The BET specific surface areas of the nanoparticles obtained by heating the mixture of the ethylene glycol solution of TIP and the NH₃ aqueous solution. Average pore diameter and total pore volume were estimated by using the BJH method to the N₂ adsorption isotherms shown in Figure 6.

The solution added to ethyleneglycol solution of TIP	[NH3] = 0.1 M	[NH3] = 1 M	H2O
𝑆BET	358 m^2/g	445 m^2/g	214 m^2/g
Average pore diameter	1.34 nm	1.17 nm	4.67 nm
Total pore volume	0.12 cm^3/g	0.13 cm^3/g	0.25 cm^3/g
