Graphene sheets are of significance in fundamental and applied science for their exceptional electronic, mechanical, and thermal properties. Among the different methods for producing graphene sheets, chemical reduction is favorable, because it can be scalable in production and versatile in realizing abundant chemical functionalization. Here, we report an environment-friendly method to produce graphene that employs Vitamin C as the reductant and amino acid as the stabilizer. This study is the first example of the use of biocompounds for nontoxic and scalable production of graphene. The graphene produced in this way has unique electrical properties that are the same as those produced via other methods. Because this reduction method avoids the use of toxic reagents, it may allow the application of graphene not only for electronic devices but also for biocompatible materials.
