摘要

水污染有几种来源。纺织、造纸和染料工业产生的偶氮染料废水是水污染的主要污染物之一。本文采用简单、快速的水热微波法制备了形态工程CuMoO4/ ZnO纳米复合材料,并将其作为光催化剂用于水污染物的降解。用x射线衍射(XRD)分析、傅里叶变换红外光谱(FT-IR)、扫描电子显微镜(SEM)、紫外可见(UV-Vis)光谱对制备的产物进行了表征。结果表明,制备的产物尺寸和形状均匀,粒径分布窄。下一步,将制备好的ZnO、CuMoO4和ZnO/CuMoO4纳米复合材料作为光降解亚甲基蓝和罗丹明b的催化剂。结果表明,ZnO/CuMoO4纳米复合材料具有优异的光催化性能。结果表明,制备的ZnO/CuMoO4纳米复合材料在紫外线照射70 min后可降解92%和84%的亚甲基蓝和罗丹明B。ZnO/CuMoO4纳米复合材料的光学特性证实了CuMoO4向ZnO的电荷转移。结果,CuMoO4中电子-空穴复合电位降低,导致价带中的空穴与纳米复合材料表面的OH基团结合形成高活性的OH•自由基。当自由基与罗丹明B和亚甲基蓝接触时,它们就会被破坏。

CuMoO4/ ZnO Nanocomposites: Novel Synthesis, Characterization, and Photocatalytic Performance
There are several sources of water contamination. One of the most important pollutant of water is azo dyes-based waste which produced by textile, paper and dye industrials. At this work, the morphological engineered CuMoO4/ ZnO Nanocomposites are prepared via simple and fast hydrothermal-microwave method and applied it as a photocaalyst for degradation of water pollutants. Prepared products is characterized with X-ray diffraction (XRD) analysis, Fourier-transform infrared spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Ultra violet-Visible (UV-Vis) spectroscopy. The results confirms that size and shape of prepared products is homogenous wih narrow size distribution. In the next step, prepared ZnO, CuMoO4, and ZnO/CuMoO4 nanocomposites were used as catalyst for photodegradation of methylene blue and Rhodamine B. Results showed that ZnO/CuMoO4 nanocomposites have excellent photocatalytic performance. Results indicated that prepared ZnO/CuMoO4 nanocomposites can be degraded 92 and 84% of methylene blue and Rhodamine B under UV irradiation after 70 minutes. The charge transfer from CuMoO4 to ZnO is confirmed by the optical characteristics of ZnO/CuMoO4 nanocomposites. As a result, the potential of electron-hole recombination in CuMoO4 decreases, resulting in holes in the valance band that combine with OH groups on the surface of nanocomposites to form highly reactive OH• radicals. The radicals are damaged when they come into contact with Rhodamine B and Methylene blue.
