▎ 摘　　要

We demonstrated a facile approach for synthesizing three-dimensional (3D), honeycomb-structured graphene scaffold in the solid flame of a (0.5+k) Zn+kCuO+ (CH2-CHCl)n reaction system. FESEM-based analyses of the acid purified porous graphene samples revealed that the synthesized graphene had a 3D, honeycomb-like structure with cell sizes of 20-100 nm and wall thicknesses of 1-3 nm. The specific surface area of the graphene sample prepared in the solid flame was about similar to 1043 m(2)/g). (C) 2014 Elsevier B.V. All rights reserved.
