High capacity gas storage in corrugated porous graphene with a specific surface area-lossless tightly stacking manner

Abstract

We report for the first time an experimental investigation of gas storage in porous graphene with nanomeshes. High capacity methane storage (236 v(STP)/v) and a high selectivity to carbon dioxide adsorption were obtained in the nanomesh graphene with a high specific surface area (SSA) and a SSA-lossless tightly stacking manner.

Hierarchically structured reduced graphene oxide/WO3 frameworks for an application into lithium ion battery anodes

“…The 3D macroscopic structure provides a high surface area, easy accessibility of ion to storage sites, short ion diffusion length to redox sites, and rapid charge and mass transport [19][20][21][22][23]. Nevertheless, to the best of our knowledge, WO 3 particles supported on 3D interconnected graphene surface as anode materials for LIBs has not been reported so far.…”

Metal etching method for preparing porous graphene as high performance anode material for lithium-ion batteries

“…[14] At the same time, other ways were also reported, including photo-etching, chemical vapor deposition and chemical activation, etc. [15][16][17][18] As the methods mentioned above, the yield is relatively low, and high-cost electron based instruments are usually employed. Therefore, it is still a great challenge on the development of low-cost, high yield and facile way to prepare high quality PG.…”

Inorganic Cryogels

“…Graphene-based cryogels have been prepared by the reduction of exfoliated graphite oxide [214][215][216][217] by templated chemical vapor deposition (CVD)-based synthesis from CH 4 on MgO catalyst [218], and by ultrasonic agitation of flake graphite in a specially selected nonpolar solvent [219]. It seems that the latter kind of cryogel is closest to graphene nanomaterials because true graphene consisting of carbon atoms should be hydrophobic [220].…”

“…Re-dispersibility of the other cryogel products in water could be realized by the oxidation of their surface. However, some of these cryogel-based materials demonstrate outstanding functional properties, such as a specific surface area of over 2,000 m 2 g À1 , high methane storage capacity [218], high electrochemical capacitance in aqueous alkaline electrolytes [214], and good electrochemical performance as anode material of Li-ion batteries [217].…”
