One-Pot Synthesis of W-TiO2/SiO2 Catalysts for the Photodegradation of p-Nitrophenol
Figure 8
A set of UV-vis spectra of p-nitrophenol aqueous solution recorded at various degradation times in the presence of the W-TiO2/SiO2 catalyst. The pH value of the solution varied from an initial to after 240 min of reaction.
