Photocatalytic Degradation of Phenol Using Immobilized Nanotube Photocatalysts
Figure 10
Effect of initial phenol concentration on the photocatalytic degradation efficiency. Experimental conditions: catalyst comprised TiO2 nanotubes, silica gel, and colloidal silica in the ratio of 3 : 2 : 20, medium pH = 3, and air flow rate = 0.3 L/min.
