Review paper: Graphene and related materials (GRMs) may play major role in energy applications

Green Car Congress

The combination of chemical functionalization and curvature control also opens new opportunities for hydrogen storage. Further, the authors note, some 2D crystals are also promising for fuel cells and in water-splitting applications because of the large photocatalytic properties of their edges. In their paper, Bonaccorso et al.
