KOH activation of carbon nanofibers

A review: methane capture by nanoporous carbon materials for automobiles

“…ACFs are attractive adsorbent materials because they have high specific surface areas and narrow pore size distributions [105][106][107][108]. In addition, the fibrous structure of ACFs is easier to handle than granular and powdered carbonaceous materials [109][110].…”

Preparation of porous diatomite-templated carbons with large adsorption capacity and mesoporous zeolite K-H as a byproduct

“…Compared activation temperature, a shorter activation time and the production of carbon materials with higher porosity [20,22,23]. Because of the higher activation capability for enhancing the porosity of carbons than that achieved with some other chemical activation agents, KOH is universally used as the chemical activation agent [21,[24][25][26][27]. However, until now, no reports have described KOH activation of diatomite-templated carbons; the activation effects and the influence of activation on the surface porosity and adsorption capacity of the carbons remain unclear, even though this information would aid in the practical application and industrial production of these carbons.…”

Transparent, flexible, and solid-state supercapacitors based on graphene electrodes

“…8,9 Supercapacitors store energy directly through the electrostatic charge accumulated at the electrode/electrolyte interfaces. 10 Carbon materials, including carbon nanotubes, 6 activated carbon, 5 carbon aerogels, 11 carbon nanofibers, 12 and templated porous carbon 13 have been extensively studied as supercapacitor electrodes because of their large specific surface area (SSA), high conductivity, lightweight, controllable pore size distribution, and chemical stability. 5 Graphene, a new carbon material having a single or few layer sp 2 carbon network, has been investigated as a new electrode material for energy storage due to its large electrical conductivity, high SSA along with facile manufacturing techniques.…”
