One-Pot Synthesis of Ru-Doped ZnO Oxides for Photodegradation of 4-Chlorophenol

Figure 11

(a) Fluorescence spectrum of hydroxyl terephthalic acid with 3 wt% Ru-ZnO catalyst at various irradiation times. (b) Profiles of the ^•OH radical formation on the 3 wt%Ru-ZnO catalyst and TiO₂-P25 in the absence 4 chlorophenol. The ^•OH radical formation was also measured in the absence of catalyst (photolysis).
