Green synthesis of MnO2 nanorods using Phyllanthus amarus plant extract and their fluorescence studies
The present work describes a facile, convenient, and green pathway for MnO2 nanoparticles (MnNPs) synthesis using manganese acetate salt as a precursor and methanolic extract of Phyllanthus amarus as a reducing agent. Curcumin extracted from turmeric was used as a stabilizing agent. The characteriza...

The present work describes a facile, convenient, and green pathway for MnO2 nanoparticles (MnNPs) synthesis using manganese acetate salt as a precursor and methanolic extract of Phyllanthus amarus as a reducing agent. Curcumin extracted from turmeric was used as a stabilizing agent. The characterization of MnNPs was performed using ultraviolet-visible (absorption and emission), Fourier transformed-infrared (FT-IR), thermogravimetric analysis, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), and selected area electron diffraction pattern (SAED) techniques. The vibrational mode of O–Mn–O observed at around 580 cm−1 in the FT-IR spectra confirms their occurrence. The morphology of MnO nanorods was investigated from Scanning electron microscopy (SEM) and TEM studies. The diffraction patterns revealed the crystalline nature of MnO2. The solid-state fluorescence investigations of MnNPs exhibited an emission intensity at 518 nm revealing the crystallinity of the sample. The results emphasized the potent application of Phyllanthus amarus extract for the synthesis of MnNPs with economic viability and ease in scaling up for mass production. |
