Hydrogen storage in high surface area graphene scaffolds.
Using an optimized KOH activation procedure we prepared highly porous graphene scaffold materials with SSA values up to 3400 m(2) g(-1) and a pore volume up to 2.2 cm(3) g(-1), which are among the highest for carbon materials. Hydrogen uptake of activated graphene samples was evaluated in a broad temperature interval (77-296 K). After additional activation by hydrogen annealing the maximal exce...
متن کاملUltrahigh surface area polypyrrole-based carbons with superior performance for hydrogen storage
Ultrahigh surface area carbons (3000 – 3500 m g) have been obtained via chemical activation of polypyrrole with KOH. The carbon materials exhibit large pore volumes (up to ~2.6 cm g) and possess two pore systems; one of pores in the micropore range (~ 1.2 nm) and the other in the small mesopore range (2.2 – 3.4 nm). Some carbons also possess a significant proportion of 0.6 nm pores. Tunning of ...
متن کاملConstruction of high-energy-density supercapacitors from pine-cone-derived high-surface-area carbons.
Very high surface area activated carbons (AC) are synthesized from pine cone petals by a chemical activation process and subsequently evaluated as an electrode material for supercapacitor applications in a nonaqueous medium. The maximum specific surface area of ∼3950 m(2) g(-1) is noted for the material treated with a 1:5 ratio of KOH to pine cone petals (PCC5), which is much higher than that ...
متن کاملThe Storage of Hydrogen in Nanoporous Carbons
An efficient storage of hydrogen is a crucial requirement for its use as a fuel in the cars of the future. Experimental and theoretical work has revealed that porous carbons are promising materials for storing molecular hydrogen, adsorbed on the surfaces of the pores. The microstructure of porous carbons is not well known, and we have investigated a class of porous carbons, the carbide-derived ...
متن کاملCO, Adsorption Techniques On High Surface Area Activated Carbons
For years the subject of CO, adsorption on activated carbons has been both challenged and supported. The question remains whether or not CO, is a valid adsorbate for characterizing pore structures of activated carbons. The predominance of nitrogen adsorption as a routine experimental technique for BET surface area approximations has more or less overshadowed the limitations of this technique in...
