Are There Any Modifications to the Original Hummers' Method?
Yes, several modifications have been proposed to improve the original Hummers' Method. For instance, the Improved Hummers' Method involves the use of additional oxidizing agents like phosphoric acid (H3PO4) to enhance the oxidation efficiency and reduce the formation of hazardous gases. Another modification employs ultrasonication to exfoliate the graphite more effectively, resulting in higher quality graphene oxide.
