Green Synthesis, Hibiscus rosa-sinensis, Nano Cobalt OxideAbstract
This research article provides the synthesis and characterization of Cobalt Oxide nano particles by eco-friendly green chemistry method. The cobalt oxide nano particles were synthesised by using leaf extract of Hibiscus rosa-sinensis. The light violet coloured leaf extract of hibiscus rosa-sinensis was used as catalyst and stabilizer for the synthesis of nano particles from precursor cobalt chloride hexa hydrate. So obtained cobalt oxide nano particles were characterized by EDAX, SEM, XRD, FTIR, TGA. EDAX confirms the presence of cobalt and oxygen in the nano particles. SEM studies shows the sponge and few cubical spine like structure of cobalt oxide with average grain size of 60 nm. XRD studies confirms the nano size of particles and maximum peak was obtained at (311) confirms the presence of nano cobalt oxide.
