MULTIFUNCTIONAL NANOCOMPOSITES Fe3O4/ZnO: SYNTHESIS, CHARACTERISTIC FOR WASTEWATER TREATMENT

Abstract

Using nanotechnology, nanomaterials in wastewater treatment is a hot topic, attractive many researchers in the world. In this paper, magnetic - semiconductor Fe₃O₄/ZnO nanocomposites were synthesized by simple, cheap chemical methods. The results of compositions, structure, morphology of the Fe₃O₄/ZnO nanocomposites are evidence to show these nanocomposites containing two phases: the magnetism of Fe₃O₄, and the semiconductor of ZnO. The as-prepared Fe₃O₄/ZnO nanocomposites simultaneously exhibit ultraviolet wavelengths absorption, and superparamagnetic property suitable for adsorption, photocatalysis, and purifications in wastewater treatment.
