摘要

如今,纳米颗粒由于其明确的物理和化学性质,在各种学科中获得了巨大的重要性。有许多物理和化学方法可用于合成金属纳米颗粒。但这些方法也存在一些缺点,如有害毒素在材料表面的吸附、高资本投资、高制造能源需求等,使其几乎不可能有效实施。合成纳米颗粒以避免上述缺点的另一种方法是在含水条件下使用植物的不同部分。植物介导的纳米颗粒合成方法因其反应速度更快、价格实惠、环保和植物多样性丰富而越来越受欢迎。采用液相色谱-质谱技术对植物提取物的化学成分进行了检测。贵金属,如银、金、铁、铜、铂、锌、钯及其氧化物,由于其巨大的潜在应用,被用于制造金属纳米颗粒。在一步绿色合成过程中,植物提取物中存在的植物化学成分将金属盐还原为金属纳米颗粒。本文概述了植物介导合成的金属和金属氧化物纳米颗粒及其不同技术的表征,以及它们的性质和在许多领域的应用。

Plant extract mediated synthesis of metal nanoparticles, their characterization and applications: A green approach
Nowadays, nanoparticles are gaining enormous importance in a wide variety of disciplines due to their unambiguous physical and chemical properties. There are lots of physical and chemical approaches available for the synthesis of metal nanoparticles. But there are certain disadvantages associated with these methods, such as adsorption of hazardous toxins on the surface of the material, high capital investment, high manufacturing energy demand, etc., which make their effective implementation almost impossible. An alternative method of synthesizing nanoparticles to avoid the aforementioned disadvantages is to use different parts of the plant under aqueous conditions. Plant-mediated approach for the synthesis of nanoparticles is becoming increasingly popular due to its faster reaction rate, easily affordable, eco-friendly nature and rich diversity of plants. Chemical compositions of plant extracts are examined using the liquid chromatography-mass spectrometry technique. Noble metals such as Silver, Gold, Iron, Copper, Platinum, Zinc, Palladium, and their oxides are used for the fabrication of metal nanoparticles, due to their enormous potential applications. In a single-step green synthesis process, the phytochemical constituents which are present in plant extract reduce metal salts into metal nanoparticles. This article gives an overview of plant-mediated synthesized metal and metal oxide nanoparticles and their characterization by using different techniques, together with their properties and applications in numerous fields.
