Question 1

What is not part of the sol-gel process for the production of titania?
◦ (HO)3-Ti-OH + HO-Ti-(OH)3 → (HO)3-Ti-O-Ti(OH)3 + H2O
◦ TiCl4 + 4 HOCH2CH3 + 4 NH3 → Ti(OCH2CH3)4 + 4 NH4Cl (in benzene)
◦ Ti(OCH2CH3)4 + 4 H2O → Ti(OH)4 + 4 HOCH2CH3
◦ 4 Ti(OH)4 + heat → 2 Ti2O3 + 8 H2O + O2

Question 2

Silica (SiO2) can be prepared from silicon ethoxide by the sol-gel process. Write a balanced equation for the hydrolysis of silicon ethoxide.
◦ Si(OCH2CH3)4 + 4 H2O → Si(OH)4 + 4 HOCH2CH3
◦ SiCl4 + 4 HOCH2CH3 + 4 NH3 → Si(OCH2CH3)4 + 4 NH4Cl (in benzene)
◦ Si(OCH2CH3)4 + 4 HOCH3 → Si(OCH3)4 + 4 HOCH2CH3
◦ Si(OCH3)4 + 4 H2O → Si(OH)4 + 4 HOCH3
