Abstract

Nanoparticles are particles at the nanometer scale, approximately 1 to 100 nm, that can be synthesized using various methods, one of which is the biological method. The biosynthesis method can be carried out using organic materials that contain antioxidant compounds that serve as bioreductors. The requirement for choosing a bioreductor is that it must have -OH groups attached to secondary carbon atoms, which can bond with metal ions to form metals, while the compounds with -OH groups themselves will be oxidized. The bioreductor in this study used extracts from corn leaves. Subsequently, the extract was synthesized with a precursor solution of Zinc Nitrate Hexahydrate to form ZnO nanoparticles. The SEM results from the precursor concentration sample of 0.3M and calcination temperature of 700˚C show particle morphology in a hexagonal shape. The EDX analysis results indicate that the sample's composition of ZnO nanoparticles consists of 76.43% atomic weight Zn and 23.57% atomic weight O. The XRD results on the sample with a precursor concentration of 0.3M at a calcination temperature of 300˚C showed that the sample was not pure ZnO, while at a calcination temperature of 700˚C, the sample indicated pure ZnO with an elemental composition of 80.3% atomic weight of Zn and 19.7% atomic weight of O. The crystal diameter size from the XRD analysis on the sample with a precursor concentration of 0.3M at calcination temperatures of 300˚C and 700˚C were 40.8564 nm and 31.7203 nm, respectively. The crystal density from the XRD analysis on the sample with a precursor concentration of 0.3M at calcination temperatures of 300˚C and 700˚C had the same value of 5.68 g/cm3, in addition, both samples had the same crystal system, which is hexagonal zincite.
