This review provides a background on the structure and properties of ZnO nanostructures. ZnO nanostructures are advantageous for many applications in sensing, photocatalysis, functional textiles, and cosmetic industries, which are described in this review. Previous work using UV Visible (UV-vis) spectroscopy and scanning electron microscopy (SEM) for ZnO nanorod growth analysis in-solution and on a substrate for determination of optical properties and morphology is discussed, as well as their results in determining the kinetics and growth mechanisms. From this literature review, it is understood that the synthesis process greatly affects nanostructures and properties; and hence, their applications. In addition, in this review, the mechanism of ZnO nanostructure growth is unveiled, and it is shown that by having greater control over their morphology and size through such mechanistic understanding, the above-mentioned applications can be affected. The contradictions and gaps in knowledge are summarized in order to highlight the variations in results, followed by suggestions for how to answer these gaps and future outlooks for ZnO nanostructure research.
本综述提供了有关氧化锌纳米结构的结构和性质的背景信息。氧化锌纳米结构在传感、光催化、功能性纺织品和化妆品行业的许多应用中具有优势，本综述对此进行了描述。讨论了先前使用紫外可见（UV-vis）光谱和扫描电子显微镜（SEM）对溶液中和衬底上的氧化锌纳米棒生长进行分析以确定光学性质和形态的工作，以及它们在确定动力学和生长机制方面的结果。通过该文献综述可知，合成过程对纳米结构和性质有很大影响，进而影响其应用。此外，本综述揭示了氧化锌纳米结构的生长机制，并表明通过这种机理理解对其形态和尺寸进行更好的控制，可以影响上述应用。总结了知识上的矛盾和差距，以突出结果的差异，随后提出了如何填补这些差距的建议以及氧化锌纳米结构研究的未来展望。
