Synthesis of Titania Nanotubes and its Application on Oxalic Acid Removal from Aquatic Environment

Abstract:

Titania nanotubes were synthesized after the protonation and calcination of titanate precursors prepared at different hydrothermal temperatures. Calcination of the titanate precursors at various temperature, governs the TiO₂ nanotubes formation. It was observed that sample prepared at 130°C and calcination at 500°C forms only anatase, but at 800°C, both anatase and rutile formed. The as-prepared titania nanotubes were used as photocatalyst in order to degrade organic contaminant, oxalic acid from aqueous solution by UV irradiation. 78 % oxalic acid was removed from the aqueous media at the nanotubes dose of 2 g L^-1, in 120 min.
