Microwave synthesis of micro-mesoporous activated carbon xerogels for high performance supercapacitors

Application of biomass-derived flexible carbon cloth coated with MnO2 nanosheets in supercapacitors

“…It should be noted that due to their intrinsic isolating nature, these structures can only act as free-standing frameworks and they usually have to be coated with a layer of conductive CNTs or GNs for further applications. Carbon skeletons have been obtained through the carbonization of melamine resin sponge [36e38], phenolic resin foam [39], cellulose paper [40] and cotton textile [41] owing to the high carbon contents of these materials. The as-synthesized carbon structures can be used as both hierarchical substrates and continuous conductive networks.…”

Desiccant capability of organic xerogels: Surface chemistry vs porous texture

“…carbon xerogel) causes these labile oxygen surface groups to be released, leading to a more condensed carbonaceous structure consisting of about 95% wt. C, the remaining being divided between H and O [23]. Therefore the surface chemistries of organic and carbon xerogels are totally different, even though their designed porosities may be similar [33,34].…”

Lignite-derived high surface area mesoporous activated carbons for electrochemical capacitors

“…ECs have widespread applications in the hybrid electric vehicles, portable electronics, high power electronic devices and uninterruptable power supplies [4]. The performance of ECs is greatly affected by the structure and property of their electrode materials, such as activated carbons (ACs), carbon nanotubes, carbon aerogels, graphene, transition metal oxides and conducting polymers [5][6][7][8][9][10][11]. Among these materials, ACs derived from various carbonaceous precursors are preferred due to their high surface area, superior chemical stability, excellent conductivity as well as relatively low cost and good accessibility [12,13].…”
