Photocatalytic Active Coatings for Lignin Degradation in a Continuous Packed Bed Reactor

Figure 7

Effect of different catalyst on percentage degradation of lignin sulfonate under UV light at wavelength 203 nm (lignin sulfonate concentration: 0.5 g/L in 200 mL, reaction time: 20 h, reaction at room temperature, and UV radiation (280–420 nm)).
