Photocatalytic Degradation of Phenol Using Immobilized Nanotube Photocatalysts
Figure 7
Photocatalytic degradation of aqueous phenol solution at different colloidal silica loading. Conditions: TiO2 nanotubes and silica gel in the catalyst were 0.12 and 0.08 g/L, respectively, air flow rate = 0.3 L/min, initial phenol concentration = 30 mg/L, and medium pH = 3.
