UV-Irradiated Photocatalytic Degradation of Nitrobenzene by Titania Binding on Quartz Tube
Figure 2
UV photocatalytic degradation of nitrobenzene at pH 4 (blue line with square symbols), 7 (green line with triangle symbols), and 11 (orange line with round symbols) with 0.2 g TiO2 at 30°C and the air feeding of 150 mL min−1 for 3 h. Concentrations of reaction intermediates nitrate (red line with empty circles) and nitrite ions (blue line with empty squares) at pH 7 are corresponded to the right ordinate as time changes.
