Photocatalytic Degradation of Phenol Using Immobilized Nanotube Photocatalysts
Figure 9
Influence of air flow rate on the photocatalytic degradation of aqueous phenol solution. Experimental conditions: catalyst comprised TiO2 nanotubes, silica gel, and colloidal silica in the ratio of 3 : 2 : 20, medium pH = 3, and initial phenol concentration = 30 mg/L.
