Titania-Coated Alumina Foam Photocatalyst for Memantine Degradation Derived by Replica Method and Sol-Gel Reaction.

In the present work, alumina (AlO) foam was prepared by the replica method where a polyurethane (PU) foam (30 pores per inch (ppi)) template was impregnated with a 60 wt.% AlO suspension. Sintered AlO foam was used as substrate for the deposition of sol-gel derived titania (TiO) film using dip coating.
