چکیده

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 the carbon textural properties was achieved through control of the activation parameters (temperature and 10

Erratum: 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. ...

Facile preparation of hierarchically porous carbons from metal-organic gels and their application in energy storage

Porous carbon materials have numerous applications due to their thermal and chemical stability, high surface area and low densities. However, conventional preparing porous carbon through zeolite or silica templates casting has been criticized by the costly and/or toxic procedure. Creating three-dimensional (3D) carbon products is another challenge. Here, we report a facile way to prepare porous...

Diamond - like carbon for data and beer storage

Carbon is a very versatile element that can crystallize in the forms of diamond or graphite. There are many noncrystalline carbons, known as amorphous carbons. An amorphous carbon with a high fraction of diamond-like (sp3) bonds is named diamond-like carbon (DLC). Unlike diamond, DLC can be deposited at room temperature. Furthermore, its properties can be tuned by changing the sp3 content, the ...
