Present work deals with synthesis of copper nanoparticles at the room temperature, using two aqueous extracts prepared from green and dry leaves of Aloe vera and Geranium (Pelargonium graveolens). Finely cut leaves were placed in the flask with the distilled water. The mixture was boiled for 15 min at the temperature of 60°C. After boiling, the mixture was centrifuged and pure extract was used for copper nanoparticles synthesis. The source of copper ions was leaching solution obtained from the bioleaching of copper shale (Kupferschiefier) using chemolithotrophic bacteria such as Acidithiobacillusfrerooxidans. The bioleaching procedure was performed in the column reactor.


Morphology controlled copper nanoparticles synthesis has been carried out by electrolytical method with various capping agents such as ethanediol, DMF and milk, The results of these nanoparticles are compared with the nanoparticles that we obtained without any capping agents. The morphological variations have been monitored by the SEM. Interestingly, this electrolytical synthetic route produced many different morphologies depending on the capping agents or hydrophobic envirnoment. We believe that hydrophilic or the hydrophobic environment may the deciding factor for the determination of the morphology and our hypothesis has been examined using hydrophilic ethandiol and DMF and with hydrophobic milk. Both ethandiol and DMF produced grapes like structure, while the milk produced multifaceted crystalline structures as confirmed by the SEM. In conclusion, natural sources such as milk produced uniform sized microparticles with many interesting features..
