Facile Synthesis of Titania Monolith and the Investigation of its Photocatalytic Activity

Abstract

In this research, we have synthesized pure monolithic titania using nanocasting technology with hydrophilic urea formaldehyde resin as a template. Powder X-ray diffraction and scanning electron microscopy results have shown that the titania monolith has interwoven skeletons and textural pores, and the crystalline is anatase. The prepared titania monolith was employed as a photocatalyst under UV light by using methyl orange (MO) as a target. Photocatalytic results showed that concentration of the MO solution decreased nearly 87% after 60 min of degradation, and after four repeated cycles of reuse, photocatalytic activity of the regenerated catalyst showed no significant change.
