Preparation of Three-Layer Graphene Sheets from Asphaltenes Using a Montmorillonite Template

Preparation of Three-Layer Graphene Sheets from Asphaltenes Using a Montmorillonite Template

We propose a novel approach to synthesize graphene sheets with fine quality by calcinating the composites intercalated with montmorillonite (MMT) and asphaltene. The graphene sample thus fabricated could reach 10.79 μm long, with smooth and continuous morphology and with little defects. By analyzing...
