摘要

研究人员对利用植物资源开发金属基纳米粒子非常感兴趣,因为它们环保、成本低且更简单。本研究利用 D. indica 和 M. micrantha 的叶片分别合成了氧化锌纳米粒子(D-ZnONPs 和 M-ZnONPs),并研究了它们对各种细菌菌株生长抑制和光催化的影响。傅立叶变换红外光谱在紫外-可见光波长 373 纳米处显示出独特的表面等离子体共振(SPR)波段,在 450-480 cm-1 处显示出与 Zn-O 伸展相应的波段,从而证明了 ZnONPs 的形成。经电子显微镜确认,生成的 ZnONPs 呈球形,平均粒径为 30 纳米,也证实了其结晶性。在自然日光下,两种 ZnONPs 在 100 分钟内对亚甲蓝(MB)的降解效率都达到了 96-99% 左右。此外,值得注意的是,与抗生素相比,两种合成的 ZnONPs 在抑制各种病原菌菌株生长方面的功效均为 55-60%。总之,可以利用植物资源大规模生产 ZnONPs,并将其作为主要成分用于环境修复和化妆品行业。

Green Synthesis of Zinc Oxide Nanoparticles Using Dillenia Indica and Mikania Micrantha Leaf Extracts: Applications in Photocatalysis and Antibacterial Activity.

Researchers are keenly interested in developing metal-based nanoparticles using plant sources as they are eco-friendly, less expensive and simpler. Zinc oxide nanoparticles, symbolized as D-ZnONPs and M-ZnONPs were synthesized in this study utilizing the leaves of D. indica and M. micrantha, respectively, and studied their impact on the growth inhibition of various bacterial strains and on the photocatalysis. By displaying the distinctive surface plasmon resonance (SPR) band at 373 nm in UV-Vis and bands at 450-480 cm-1 corresponding to Zn-O stretching FTIR spectroscopy imparted the formation of ZnONPs which was further supported by X-ray diffraction analysis by showing the polycrystalline nature and a hexagonal wurtzite structure. The spherical form and average particle size of 30 nm of the produced ZnONPs, as confirmed by electron microscopy, are also confirmed to be crystalline. Under natural sunlight, both ZnONPs demonstrate excellent degradation efficacy about 96-99 % within 100 min towards methylene blue (MB). Furthermore, it is noteworthy that both the synthesized ZnONPs exhibited 55-60 % efficacy with respect to antibiotics in inhibiting the growth of various pathogenic bacterial strains. Overall, ZnONPs can be produced on a large-scale using plant sources and employed them in environmental remediation and cosmetic industries as prominent components.

期刊介绍: ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
