Investigation of the Reduction of Graphene Oxide by Lithium Triethylborohydride

Abstract EN

The chemical reduction of a wet colloidal suspension of graphene oxide is a cost-effective and adaptable method for large scale production of “quasi” graphene for a wide variety of optoelectronic applications.

In this study, modified Hummers’ procedure was used to synthesize high quality graphene oxide at 50°C.

This modified protocol thus eliminates the potentially hazardous second high-temperature step in Hummers’ method for the production of GO.

Furthermore, the reduction of graphene oxide by lithium triethylborohydride is demonstrated for the first time.

According to FT-IR, UV-Vis, TGA, Raman, SEM/EDS, and AFM results, the reduced graphene oxide (LiEt3BH-RGO) has properties comparable to other reduced graphene oxide products reported in the literature.
