High-efficient Synthesis of Graphene Oxide Based on Improved Hummers Method
Inner Mongolia University of Science and Technology
Abstract
Abstract As an important precursor and derivate of graphene, graphene oxide (GO) has received wide attention in recent years. However, the synthesis of GO in an economical and efficient way remains a great challenge. Here we reported an improved NaNO 3 -free Hummers method by partly replacing KMnO 4 with K 2 FeO 4 and controlling the amount of concentrated sulfuric acid. As compared to the existing NaNO 3 -free Hummers methods, this improved routine greatly reduces the reactant consumption while keeps a high yield. The obtained GO was characterized by various techniques, and its derived graphene aerogel was demonstrated as high-performance supercapacitor electrodes. This improved synthesis shows good prospects…
