Photocatalytic Degradation of Phenol Using Immobilized Nanotube Photocatalysts
Figure 8
Effect of medium pH on the photocatalytic degradation of aqueous phenol solution. Conditions: catalyst comprised TiO2 nanotubes, silica gel, and colloidal silica in the ratio of 3 : 2 : 20, air flow rate = 0.3 L/min and initial phenol concentration = 30 mg/L.
