One-Step Green Synthesis and Characterization of Flower Extract-Mediated Mercuric Oxide (HgO) Nanoparticles from Callistemon Viminalis.


The present study demonstrates green synthesis of nanosized HgO using flower extract of an ornamental plant callistemon viminalis. Till date, there is no report of synthesis of Nano particles utilizing an aqueous flower extract of callistemon viminalis. In this research work, callistemon viminalis flower extract in a concentrated aqueous solution of mercury (II) acetate results in HgO Nano particles. Mercuric acetate was taken as the metal precursor whereas flower extract act as a reducing as well as a stabilizing agent. The phytochemicals present in the extract act as a reducing agents, which include saponins, phenolic compounds, and flavonoids. The formation of the HgO nanoparticles was monitored by using UV-Vis absorption spectroscopy and FTIR.
