Research on Preparation and Morphology of GO and GO/Fe₃O₄ Composite

Abstract:

Graphite oxide was prepared from 325 mesh graphite (G) in this paper with methods of Hummers method,sulphuric/phosphoric acid method and reaction kettle method, the Graphene Oxides (GO) were obtained with ultrasonic treatment. Then Fe₃O₄ particles of two different proportions and hydrazine hydrate were introduced into one of the GO to obtain GO/Fe₃O₄ composites. X-ray diffraction (XRD) was used to characterize the G,the obtained graphite oxide and GO/Fe₃O₄ respectively. Scanning electron microscopy (SEM) was used to characterize the obtained GO and GO/ Fe₃O₄ composites.The results show that the GO obtained by the way of sulphuric/phosphoric acid has the best pattern and the nanoparticle scale decreased as the proportion of GO in GO/Fe₃O₄ increased.
