Graphene oxide synthesizing by hummer method
WebFeb 19, 2024 · In this study, graphene oxide was synthesized from recycle carbon of waste tyre using modified Hummer’s method. The morphology and structural properties of the graphene oxide were investigated using Raman spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). WebDec 19, 2011 · Marcano et al 19 recently reported the synthesis of GO using an improved Hummer’s method. This method introduced a relatively simple oxidation process, with temperature controlled at 50°C, which was rather low compared with the previously reported temperature of 95°C. However, the washing process was time-consuming and tedious.
