From date syrup to three-dimensional graphene network

Abstract

As a three-dimensional nano-materials, graphene foam is regarded as an ideal choice for a wide array of critical applications due to its porous structure and high surface area. In this study, the main objective is a synthesis of graphene foam via a simple, low-cost, and eco-friendly approach. Graphene foam is synthesized from date-syrup DS which is used as a carbon-enriched source using potassium chloride KCl particles as a scaffold on which graphene layers are built via dehydration and graphitization processes. Characteristic analyses revealed that the Date-Derived-Graphene-Foam DDGF is indeed graphenic material with G and D bands at 1598 cm-1 and 1350 cm-1, respectively with layered and porous structure. The lateral size of the obtained DDGF is determined to be ~6nm. This quick, simple and eco-friendly approach can be good potential in the high-yield production of graphenic-foam.
