Porous graphene material, named as MWRGO, has been prepared by microwave-assisted reduction method. Extensive characterizations indicate that graphene oxide was effectively reduced and MWRGO has a porous and disordered stacking structure. It has a special surface area of 461.6 m2/g with pore size centered at 0.67 nm. H2 and CO2 adsorption properties of MWRGO were investigated, showing a H2 uptake of 0.52 wt% at 77 K and 1 atm and an absolute adsorption amount as high as 10.7 wt% at a higher pressure of 60 bar. The amount of CO2 adsorption at 273 K and 1 atm is 7.1 wt%.
