Improved Synthesis of Graphene Oxide

An improved method for the preparation of graphene oxide (GO) is described. Currently, Hummers' method (KMnO 4, NaNO 3, H 2 SO 4) is the most common method used for preparing graphene oxide.We have found that excluding the NaNO 3, increasing the amount of KMnO 4, and performing the reaction in a 9:1 mixture of H 2 SO 4 /H 3 PO 4 improves the efficiency of the oxidation process.

Self

Flower-like graphene/CuOCu-BTC (GR/CuOCu-BTC) composite was employed as electrode material for the voltammetric determination of caffeic acid (CA) in the wine. The composite material was prepared via the self-template method. In this synthetic process, budlike CuO not only acts as the template, but also provides Cu2+ ions for in situ growth of the Cu-BTC shell. The utilization of GR as
