Mass production of porous carbon at low cost for supercapacitor applications is highly desired. Herein, for the first time we report a novel method to grow porous 3D graphene by using Mg to reduce CS2 vapor. In a tube furnace the mixture of Mg and NaCl powders are heated at 570 oC and reacted with CS2 vapor carried by an Ar flow. The Mg powder can be about 95% consumed and the weight of resultant carbon nanomaterial is in gram scale after one experiment. This 3D graphene product with specific surface area of 980 cm2/g is processed into electrodes for electrochemical test, showing a specific capacitance of 212 F/g at 1 A/g in H2SO4 aqueous electrolyte. Besides, the electrode is continuously charged/discharged at 5 A/g for 10,000 cycles and its capacitance remains 98.5% of the original value.

Nanoporous structures exhibit great application potential in the biosensing, energy storage and other nanoelectronics. As a newly discovered 2D material with extraordinary properties, graphene presents the ability to hold a nanoporous structure which could overcome the inherent shortages for most of the existing nanoporous materials. While how to efficiently synthesize the nanoporous structures in graphene and how to further expand the applications of nanoporous graphene (NPG) are still big challenges. In this paper, we reviewed the recent advancements related to the synthesis and potential applications of NPGs. By analyzing the different approaches to fabricate the NPGs, and the research trends for the application realization of NPG, we aim at stimulating further research on this subject.
