Facile and green synthesis of silver nanoparticles using oxidized pectin

In the current work, an alternative route for facile synthesis of nanosilver is reported. Oxidized pectin has been used as the reducing agent as well as the stabilizing agent, resulting in the formation of oxidized pectin-nanosilver (OP-NS) core sheath nanohydrogels. The effect of reaction parameter...

Description
Summary:In the current work, an alternative route for facile synthesis of nanosilver is reported. Oxidized pectin has been used as the reducing agent as well as the stabilizing agent, resulting in the formation of oxidized pectin-nanosilver (OP-NS) core sheath nanohydrogels. The effect of reaction parameters on the synthesized nanoparticles is investigated. The structural and morphological features have been analyzed using X-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM) respectively. The crystal size of the synthesized nanosilver was calculated to be 28.76nm. While the average size of the core sheath structure varied from 289nm to 540nm, the size of the silver nanoparticle entities at the core varied from 100nm to 180nm, with variation in reaction time. From the morphological examination, it could be seen that flower like nanostructures are formed with nanosilver in the core surrounded by a polymeric halo. [Display omitted] •In-situ reduction of silver nitrate to nanosilver was carried out using oxidized pectin.•Oxidized pectin-nanosilver nanohydrogels were synthesized.•Nanoparticles with flower like morphology and face centered cubic crystal structure were fabricated.
