In this review, we provide an overview of recent progress in the synthesis, structural characterization, and application of electrochemical and mechanical devices of 3D-ordered porous graphene material nanostructures. The remainder of this paper is organized as follows: In Section 2, we discuss typical synthetic procedures using templating carbonization on nanostructured precursor materials, such as zeolite and alumina. We then focus on the reaction mechanism of the carbon growth mechanism of CH4-CVD on alumina and the structure of the resultant 3D graphene, directed toward achieving a periodically ordered graphene nanostructure (Fig. ). In Section 3, we provide an overview of how the 3D continuous nature of porous graphene drives its potential applications in electric double-layer capacitors, next-generation Li-ion batteries, and refrigeration devices based on mechanical force. In Section 4, we summarize this review and describe our outlook for further fundamental and application studies on 3D-ordered graphenes in the near future.
