A critical investigation on the fabrication of metal oxide nanoparticles (NPs) such as ZnO, SnO, and CeO NPs synthesized from green and phytogenic method using plants and various plant parts have been compiled. In this review, different plant extraction methods, synthesis methods, characterization techniques, effects of plant extract on the physical, chemical, and optical properties of green synthesized ZnO, SnO, and CeO NPs also have been compiled and discussed. Effect of several parameters on the size, morphology, and optical band gap energy of metal oxide have been explored. Moreover, the role of solvents has been found important and discussed. Extract composition i.e. phytochemicals also found to affect the morphology and size of the synthesized ZnO, SnO, and CeO NPs. It was found that, there is no universal extraction method that is ideal and extraction techniques is unique to the plant type, plant parts, and solvent used.
对使用植物和各种植物部分通过绿色和植物源方法合成的金属氧化物纳米粒子（NPs）如 ZnO、SnO 和 CeO NPs 的制备进行了批判性研究。在这篇综述中，还编译和讨论了不同的植物提取方法、合成方法、表征技术、植物提取物对绿色合成 ZnO、SnO 和 CeO NPs 的物理、化学和光学性质的影响。研究了几种参数对金属氧化物尺寸、形态和光学带隙能量的影响。此外，还发现溶剂的作用很重要，并进行了讨论。提取物成分，即植物化学物质，也被发现会影响合成的 ZnO、SnO 和 CeO NPs 的形态和尺寸。结果发现，没有一种通用的理想提取方法，提取技术是针对植物类型、植物部分和使用的溶剂而独特的。
