From date syrup to three-dimensional graphene network

Abstract

As a three-dimensional nano-material, 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 have revealed that the Date-Derived-Graphene-Foam (DDGF) is indeed graphene material with G and D bands at 1598 cm−1 and 1350 cm−1, respectively, with a layered and porous structure. The lateral size of the obtained DDGF is determined as ∼6 nm. This quick, simple, and eco-friendly approach can be considered as having good potential in the high-yield production of graphene foam.
