摘要： 纳米氧化锌是一类多功能纳米材料，由于其优秀的物理化学性质而被广泛应用于多个领域。传统的合成方法存在成本过高、过程复杂、产物不稳定等问题。微乳合成法具有操作简单，成本低廉，产物尺寸可控等优点，可以有效避免传统合成方法的缺陷。特别是将废弃大豆油合成的乳化剂应用在合成的过程中，可以实现废物的回收再利用，又能满足绿色化学和可持续发展的要求。使用X射线衍射(XRD)、扫描电镜(SEM)、化学分析等多种方法对产物纳米氧化锌的形貌和性质进行了表征，实现了无机合成-化学分析-仪器分析的综合偶联，从而达到提升大学生进行综合实验能力的目的。

Abstract: Nanoscale zinc oxide is a multifunctional nanomaterial extensively utilized across various domains due to its exceptional physicochemical properties. Traditional synthesis methods often face challenges such as high costs, complex procedures, and product instability. The microemulsion synthesis overcomes these issues, offering simplicity, cost-effectiveness, and controllable produce dimensions. Notably, the use of waste soybean oil as an emulsifier in the synthesis process aligns with the principles of green chemistry and sustainable development, highlighting waste material reuse. The nanoscale zinc oxide products were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and chemical analysis. This approach fosters a comprehensive integration of inorganic synthesis, chemical and instrument analysis, aiming to enhance the holistic experimental capabilities of university students.
