Phyllanthus emblica Mediated Silica Nanomaterials: Biosynthesis, Structural and Stability Analysis

The current investigation reports on a green route, simple and eco-friendly method for synthesis of silica nanoparticles from Phyllanthus emblica. Appropriate characterization techniques were employed to assess the nature, microstructure, size, purity, elemental composition and stability of as-biosynthesized silica nanoparticles. The XRD analysis showed a wide-ranging peak at 22 circle of 2 theta value and proved that the nanoparticles were nature with 1.2 nm average size of particles. FT-IR studies confirmed the occurrence of metal oxide group and presence of phyto-molecules namely hydroxyl, amide, and carboxyl functional groups, which were responsible for formation and stabilization of silica nanomaterials. Zeta potential is stable under high temperature. EDX analysis revealed the purity of nanomaterials and spectra confirmed that formation of silica nanomaterials (72.97 weight percentage of SiO2 content) with low impurities. SEM analysis shows that the particles are spherical in shape with low agglomeration. This research work concluded that the P. emblica was an excellent and reliable green resource for production of highly stable and potential silica nanoparticles.

Automated summary
