Abstract
The development of environmentally benign, low-processing and low-cost approaches to the large-scale preparation of advanced nanomaterials based on the use of biological materials is currently attracting great interest. Here, we report the discovery that aqueous honey solutions reduce graphene oxide in a low-cost and an eco-friendly manner, yielding highly water dispersive functionalized reduced graphene sheets. The roles of honey in the reduction of graphene oxide of as-prepared graphene are demonstrated. The possible mechanism for the de-epoxidation of graphene oxide is elucidated. The fabricated a honey-reduced graphene oxide-based field-effect transistor exhibited ambipolar transfer characteristics, thereby demonstrating that the developed material may therefore have applications in electronic devices and sensors. © 2018 The Korean Society of Industrial and Engineering Chemistry.
