Abstract

Titanium dioxide (TiO₂) represents a well-studied photocatalyst that has been widely considered in research activities and is also commercialized. Because of its appealing physical and chemical properties, it was found that it can be useful in a wide spectrum of applications. The present study provides a process for the production of a porous, extruded visible light active titania-based material comprising mesopores. Today It has been surprisingly found that using a cellulose porogen during the extrusion of a titania-based material enables the formation of the mesopores following removal of the porogen by thermal or oxidative decomposition. The second aspect of the present study provides the characterization results of the prepared mesopores based on the techniques with DRS, AFM, and TEM. Finally, the photodegradation of MO dye was examined with different operational parameters such as pH, concentration of nanophotocatalyst, reusability investigated. As an excellent result, the best photocatalytic activity was measured at pH=3 with catalyst concentration of 200 mg/L and the prepared nanophotocatalyst has good reusability up to 5 runs.
