Synthesis of ZnO-gold nanoparticles composite using Hibiscus sabdariffa extract as reductor

Abstract

One of the synthesis methods currently being carried out is green synthesis. One of the efforts to implement the green method is to use plant extracts that can be renewed. Hibiscus sabdariffa is one type of plant that is able to produce anthocyanin pigments. In this study, the synthesis of ZnO composites with gold nanoparticles will be carried out using Hibiscus sabdariffa flower extract. The composites of gold nanoparticles and ZnO were determined using XRD instrumentation where there were characteristic peaks of ZnO and gold nanoparticles.
