XRD and BET Analysis of Gr and CB Samples. a Crystaline structures of Gr samples in this study consisted of two graphitic structures: hexagonal (2H) and rhombohedral (3R), where ABA and ABCA represent stacked graphitic layers. b XRD pattern of Gr20 with the Bragg lines identified with 2H, 3R, and 2H/3R phases of graphite. Gr5 and Gr1 had similar patterns, with slightly less pronounced peaks for Gr1. The XRD pattern of CB consist of broad peaks near 2-theta = 24o and 44o typical of disordered carbons. c Table summary of surface area of dry powder samples assess using the BET method and the number of layers/sheets in each sample determined by XRD
