Biosynthesis of SnO2 Nanoparticles from Plant Leaf of Chromolaena odorata (l.) King & Robinson using Different Calcination Temperatures

Abstract
Chromolaena Odorata (C. odorata) or locally known as Kapal Terbang is one of medicinal herb plant that can be found in Asia region. In this paper, we report the first time of biosynthesis of Tin Oxide (SnO2) nanoparticles (NPs) using bioactive compound from leaf extract of C. odorata which act as reducing and stabilizing agent. We have extracted the bioactive compound by using boiling method and mixed with tin chloride salt to produce SnO2 NPs. The SnO2 NPs were calcined at five different temperatures ranging from 500 to 900oC for 3 hours respectively. The synthesized SnO2 NPs were characterized using FESEM, EDX, FTIR, Raman and UV-visible spectroscopy. Among these five different temperatures, the optimum calcination temperature was found to be at 700oC for the formation of SnO2 NPs. Keywords - Biosynthesis, SnO2 nanoparticles (NPs), leaf extract, Calcination Temperature.
