A Sustainable Modified Hummers Method for Synthesizing Graphene Oxide Nanosheets

Abstract

In this study, graphite oxide (GO) nanosheets were prepared using a new modified Hummer method. This method takes less time than previous modified Hummer methods. The method requires only 6 hours to complete and still achieves a high yield of GO. Morphological and structural characteristics were investigated. GO exhibits good morphological and structural characteristics, including valuable defects (such as functional groups containing OH, COOH, and C=O) and a good graphitic structure. This modified Hummer method demonstrably mitigated waste generation and the potential for decreased time and cost requirements.
