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).本数据集包含图像与表格。为验证氧化锌-酞菁锌（Zinc Oxide-Zinc Phthalocyanine, ZnO-ZnPc）复合材料对活性蓝M-2GE（C. I. 活性蓝194）的光降解效果，本研究开展了相关实验测试，数据集内收录了该复合材料的扫描电子显微镜（Scanning Electron Microscope, SEM）图像，以及反应时长分别为20、40、60、80、100、120、140与160分钟时，该染料降解中间产物碎片的多组气相色谱-质谱联用（Gas Chromatography-Mass Spectrometry, GC-MS）图谱。 图1(a)与(b)展示了两张ZnO-ZnPc复合材料的SEM图像，其中(a)的放大倍数为3000倍，(b)为3300倍。该SEM显微图像证实了合成所得ZnO-ZnPc复合材料的结晶特性：低倍率图像(a)可见松散的晶粒颗粒，高倍率图像(b)则清晰展现出该复合材料优异的结晶性，其颗粒尺寸处于纳米级。 本数据集的图2至图9分别对应20、40、60、80、100、120、140及160分钟时样品降解过程的气相色谱图，所有图谱均呈现出相近的保留时间峰型。图10至图17则分别对应上述各反应时长下样品降解过程的质谱图，不同时长的质谱图均呈现出相似的碎片峰特征。 通过各峰的保留时间与碎片的推测分子量分析可知，活性蓝M-2GE在降解过程中大概率分解为分子量更低的化合物。数据集内的表1汇总了各降解时段通过GC-MS鉴定得到的常见中间产物，包括苯胺（m/z 91）、硝基苯（m/z 119）、苯酚（m/z 93）、3,6,8-三羟基萘胺（m/z 191）、1,4-苯醌（m/z 109）、邻苯二甲酸（m/z 161）、马来酸（m/z 113）、草酸（m/z 87）与乙酸（m/z 57）。
