Preparation, Characterization, and Activity of Y2O3-ZnO Complex Oxides for the Photodegradation of 2,4-Dinitrophenol
Figure 5
Fluorescence spectra observed after illumination of ZnO, 0.25%-Y2O3-ZnO, 0.50%-Y2O3-ZnO, 0.75%-Y2O3-ZnO, and 1.00%-Y2O3-ZnO in 2 × 10−3 mol·L−1 NaOH solution of terephthalic acid (excitation at 315 nm) and the fluorescence spectrum of pure terephthalic acid. Each fluorescence spectrum was recorded after 30 min of UV irradiation.
