In the present work, we report on green synthesis of hybrid silver nano structures using a solution of AgNO3 and leaf broth of Cassia occidentalis plant as reducing agent. The incubation of AgNO3 solution and leaf broth for 48 hrs under neutral pH and constant stirring at 150 rpm resulted in the formation of hybrid silver nanostructures comprised of silver nano particles (AgNPs) and silver nanorods (AgNRs). The bio reduction of Ag+ ions to AgNPs and AgNRs is confirmed via appearance of surface plasmon resonance peaks at 420 and 370 nm in the UV visible spectrum. The synthesized nanostructures are purified and further characterized using XRD and FT-ATR. The morphology of nanostructures is examined by SEM studies which further revealed the formation of spherical shaped AgNPs and rod shaped AgNRs. The study therefore concludes that it is possible to synthesize the AgNRs and AgNPs effectively using silver nitrate (AgNO3) solution and the leaf broth of Cassia occidentalis. However, further work is needed to establish the employability of these nanostructures in various applications. Copyright © 2017 VBRI Press.
