In this study, a ternary nanocomposite (GO/ZnO/Ag) i.e., a graphene oxide (GO) interfaced, zinc oxide (ZnO) photocatalyst, doped with silver (Ag) is synthesized for imidacloprid (IMD) degradation. For GO synthesis, Oil Palm Empty Fruit Bunch Fiber (OPEFB) was used as its precursor for graphite preparation.
