SEM image and GC/MS data for "Photocatalysis using Zinc Oxide-Zinc Phthalocyanine Composite for Effective Mineralization of Organic Pollutants

The dataset includes figures and a table. The SEM image of ZnO-ZnPc composite and the various GC–MS figures of intermediates fragments of Reactive dark blue M-2GE (C. I. Reactive Blue 194) at 20, 40, 60, 80, 100, 120, 140 and 160 minutes (min) in an experimental test performed to ascertain the effectiveness of Zinc oxide-Zinc Phthalocyanine composite for the photodegradation of the dye is identified in the dataset. Two SEM images of the ZnO-ZnPc composite were presented in Figure 1(a) and (b) with a magnification of (a) as x 3,000 and (b) as x 3,300. The SEM micrographs indicate a crystalline nature of the synthesized ZnO-ZnPc composite. The SEM image of the ZnO-ZnPc composite at low magnification (a) shows loose grain particles. Close view at high magnification (b), shows a high crystalline nature of ZnO-ZnPc composite. The particle size was in nanoscale.
Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, Figure 8 and Figure 9 of the dataset shows the gas chromatogram of degradation of the sample at 20, 40, 60, 80, 100, 120, 140 and 160 minutes. Similar retention time peaks were obtained. Figure 10, Figure 11, Figure 12, Figure 13, Figure 14, Figure 15, Figure 16 and Figure 17 of the dataset also shows the mass spectrum of degradation of the samples at 20, 40, 60, 80, 100, 120, 140 and 160 minutes. The spectrum for the various times showed similar fragment peaks. The retention time of peaks and suggested molecular weight of fragments of these compounds indicated that in the degradation of Reactive dark blue M-2GE, were most likely broken down into compounds with lower molecular weight. Table 1 in the dataset showed the common intermediate compound identified by the GC/MS for the various degradation time. The common intermediates include analine (m/z 91), nitrobenzene(m/z 119), phenol (m/z 93), 3,6,8-trihydroxynaphthylamine (m/z 191), benzo-1,4-quinone (m/z 109), phthalic acid (m/z 161), maleic acid (m/z 113), oxalic acid (m/z 87) and acetic acid (m/z 57).
