Abstract
A porous carbon material with specific surface area of 894Â m2/g and pore volume of 0.47Â cm3/g has been easily synthesized by pyrolysis of a gel containing nickel chloride. Transmission electron microscopy reveals a texture of evenly spreading spherical mesopores and well dispersed micropores. Potassium hydroxide treatment results in a surface area and pore volume of the pristine materials of up to 2930Â m2/g and 1.52Â cm3/g, respectively. Cryogenic hydrogen uptake capacities were measured and the highest capacity of 6.24Â wt% was obtained at 77Â K under 2Â MPa.
