Abstract：
In recent years, extensive research endeavors are being undertaken for synthesis of an efficient, economic and eco-friendly cerium oxide nanoparticles (CeO2 NPs) using plant extract mediated greener approach. A number of medicinal plants and their specific parts (flowers, bark, seeds, fruits, seeds and leaves) have been found to be capable of synthesizing CeO2 NPs. The specific key phytochemical constituents of plants such as alkaloids, terpenoids, phenolic acids, flavones and tannins can play significant role as a reducing, stabilizing and capping agents in the synthesis of CeO2 NPs from their respective precursor solution of metal ions. The CeO2 NPs are frequently using in diverse fields of science and technology including photocatalytic degradation of dyes, antibiotics as well as antimicrobial applications. In this review, the mechanism behind the green synthesis CeO2 NPs using plant entities are summarized along with discussion of analytical results from characterization techniques. An overview of CeO2 NPs for water remediation application via photocatalytic degradation of dyes and antibiotics are discussed. In addition, the mechanisms of antimicrobial efficacy of CeO2 NPs and current challenges for their sustainable application at large scale in real environmental conditions are discussed.
摘要：
近年来,正在进行广泛的研究工作，以合成一种有效的，经济和生态友好的氧化铈纳米颗粒（CeO2NPs）使用植物提取物介导的绿色方法。一些药用植物及其特定部分(花，吠叫,种子,水果,已发现种子和叶子能够合成CeO2NP。植物的特定关键植物化学成分，如生物碱，萜类化合物,酚酸，黄酮和单宁可以起到显著的作用，在从各自的金属离子前体溶液合成CeO2NP中的稳定剂和封端剂。CeO2NPs经常用于科学技术的不同领域，包括染料的光催化降解，抗生素以及抗菌应用。在这次审查中,总结了使用植物实体绿色合成CeO2NP的机理，并讨论了表征技术的分析结果。概述了CeO2NPs通过染料和抗生素的光催化降解用于水修复的应用。此外,讨论了CeO2NPs的抗菌功效机理以及在实际环境条件下大规模可持续应用的当前挑战。
