Ultrahigh 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 کاملZeolite-templated carbon materials for high-pressure hydrogen storage.
Zeolite-templated carbon (ZTC) materials were synthesized, characterized, and evaluated as potential hydrogen storage materials between 77 and 298 K up to 30 MPa. Successful synthesis of high template fidelity ZTCs was confirmed by X-ray diffraction and nitrogen adsorption at 77 K; BET surface areas up to ~3600 m(2) g(-1) were achieved. Equilibrium hydrogen adsorption capacity in ZTCs is higher...
متن کاملErratum: Facile synthesis of ultrahigh-surface-area hollow carbon nanospheres for enhanced adsorption and energy storage
Exceptionally large surface area and well-defined nanostructure are both critical in the field of nanoporous carbons for challenging energy and environmental issues. The pursuit of ultrahigh surface area while maintaining definite nanostructure remains a formidable challenge because extensive creation of pores will undoubtedly give rise to the damage of nanostructures, especially below 100 nm. ...
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 کاملCharacterisation of porous hydrogen storage materials: carbons, zeolites, MOFs and PIMs.
Porous materials adsorb H2 through physisorption, a process which typically has a rather low enthalpy of adsorption (e.g. ca. 4 to 7 kJ mol(-1) for MOFs), thus requiring cryogenic temperatures for hydrogen storage. In this paper, we consider some of the issues associated with the accurate characterisation of the hydrogen adsorption properties of microporous materials. We present comparative gra...
