Abstract

ZnO nanoparticles is one of the nanomaterial have attracted attention of researcher for further investigation. ZnO nanoparticles can be synthesized by various methods with a variety of precursors, temperature, and capping agent to create the different characters. Previous research, synthesized ZnO nanoparticles carried out using synthetic compounds as capping agent. Further studies using natural compounds as capping agent needs to be done to implement research based on green-synthesis. In this research, sinthesized ZnO nanoparticles was carried out using water extracts of Sapindus rarak DC rinds leafs as capping agent. Variation concentration capping agent used was 5, 10 and 15% w/v. Synthesis is done by capping agent preparation, followed by synthesis of ZnO nanoparticles using sonochemical method. ZnO powders were characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). Characterization using XRD showed the formation of specific peak with varies crystallinity by variated concentration and type of capping agents. SEM analysis showed the different morphologies with various concentration of capping agents.
