Copper oxide nanoparticles (CuO NPs) are one of the most widely used nanomaterials nowadays. CuO NPs have numerous applications in biological processes, medicine, energy devices, environmental remediation, and industrial fields from nanotechnology. With the increasing concern about the energy crisis and the challenges of chemical and physical approaches for preparing metal NPs, attempts to develop modern alternative chemistry have gotten much attention. Biological approaches that do not produce toxic waste and therefore do not require purification processes have been the subject of numerous studies. Plants may be extremely useful in the study of biogenic metal NP synthesis. This review aims to shed more light on the interactions between plant extracts and CuO NP synthesis. The use of living plants for CuO NPs biosynthesis is a cost-effective and environmentally friendly process. To date, the findings have revealed many aspects of plant physiology and their relationships to the synthesis of NPs. The current state of the art and potential challenges in the green synthesis of CuO NPs are described in this paper. This study found a recent increase in the green synthesis of CuO NPs using various plant extracts. As a result, a thorough explanation of green synthesis and stabilizing agents for CuO NPs made from these green sources is given. Additionally, the multifunctional applications of CuO NPs synthesized with various plant extracts in environmental remediation, sensing, catalytic reduction, photocatalysis, diverse biological activities, energy storage, and several organic transformations such as reduction, coupling, and multicomponent reactions were carefully reviewed. We expect that this review could serve as a useful guide for readers with a general interest in the plant extract mediated biosynthesis of CuO NPs and their potential applications.
氧化铜纳米粒子（CuO NPs）是当今应用最广泛的纳米材料之一。CuO NPs 在生物技术、医学、能源装置、环境修复和工业领域的纳米技术中具有许多应用。由于对能源危机的日益关注以及化学和物理方法制备金属 NPs 的挑战，尝试开发现代替代化学方法引起了广泛关注。不产生有毒废物且因此不需要净化过程的生物方法已经成为许多研究的主题。植物在生物金属 NP 合成研究中可能非常有用。本综述旨在更深入地了解植物提取物与 CuO NP 合成之间的相互作用。利用活体植物进行 CuO NPs 生物合成是一种具有成本效益且环保的方法。迄今为止，这些发现揭示了许多植物生理学及其与 NPs 合成之间的关系方面。本文描述了 CuO NPs 绿色合成的最新进展和潜在挑战。本研究发现，使用各种植物提取物进行 CuO NPs 的绿色合成最近有所增加。因此，对这些绿色来源合成的 CuO NPs 的绿色合成和稳定剂进行了详细解释。此外，还仔细综述了各种植物提取物合成的 CuO NPs 在环境修复、传感、催化还原、光催化、多种生物活性、储能以及几种有机转化（如还原、偶联和多组分反应）中的多功能应用。我们希望本综述可以为对植物提取物介导的 CuO NPs 生物合成及其潜在应用有一般兴趣的读者提供有用的指南。
