Direct synthesis iron oxide nanoparticles using ramie, lemon and dragon fruit as green and low cost approach

Abstract

Plant extracts have been used as agent reduction capping to synthesise various nanoparticles due to the process is a low cost, large-scale method and environmental friendly. Herein, iron oxide nanoparticles were synthesized using ramie, lemon and dragon fruit extracts. The characterization results show that all synthesized iron oxide nanoparticles had almost similar diameters, shape and crystalline phases although different of plants extracts were used. Among the plants, ramie has cheapest market price in which the cost production of iron oxide nanoparticles can be reduced significantly.
