“…Zhao and co-workers studied the adsorption of bulky dye molecules from waste water, 76,77 where mesoporous carbons showed adsorption capacities almost twice as high as reported for conventional activated carbon. Moreover, they also demonstrated that the surface of ordered mesoporous carbon FDU-15 can be modified by wet oxidation with acidic ammonia persulfate (APS, (NH 4 ) 2 S 2 O 8 ) and HNO 3 . This surface modification further improved adsorption capacities for various metal ions, fuchsin dye and ibuprofen drug, whereas the defined mesopore structure remained intact.…”

Mesoporous carbons synthesized via a soft-templating approach have attracted much attention due to their easy synthesis and facile control over the derived pore structure. In analogy to soft-templating approaches for mesoporous metal oxides, their synthesis is based on a sequence of forming supramolecular arrangements of precursor molecules with the soft templates, stabilization of the precursor framework by polymerization and finally the removal of the templates. Using micelles of amphiphilic block-copolymers as templates, facile control over the morphology and size of mesopores can be achieved by e.g. controlling size, composition, and concentration of the template polymers or composition and degree of polymerization of the precursor. Moreover, soft templating approaches can be extended to obtain also carbon materials with hierarchical meso-and macroporosity. The additional macroporosity either can result from templating by polymer latex or is induced via macrophase separation. In this review, we describe recent progress and examples in the synthesis and application of mesoporous carbon materials based on soft-templating approaches. Moreover, we reiterate fundamental principles of self-aggregation, highlight proposed synthesis mechanisms and present means of controlling pore size, also in hierarchical meso-macroporous carbon materials.

“…Most common synthetic procedures to prepare porous carbon materials are based on: traditional chemical and physical activation (or a combination of both) of a suitable precursor [5][6][7], catalytic activation using metal salts or organometallic compounds [8][9][10][11], carbonization of polymer blends [12][13][14][15], carbonization of an organic gel synthesized under different drying conditions (xerogel, cryogel or aerogel) [16][17][18], among most representative.…”

Abstract:Synthetic nanoporous carbons are prepared by polymerization of mixtures containing coal tar pitch and furfural in different proportions, followed by carbonization of obtained solid product and steam activation of the carbonizate. The chemical composition of the initial mixture significantly affects the physicochemical properties (surface area, pore structure, electro resistance and amount of oxygen containing groups on the surface) of the obtained materials. The incorporation if oxygen in the precursor mixture by means of furfural, has a strong influence in the synthetic route; rising the furfural content facilitates the formation of a solid product characterized by a large oxygen content. Moreover, the solid product is more reactive towards activation as the furfural content increases, giving rise to nanoporous carbons with large surface areas and unique chemical features (high density of oxygen functionalities of basic nature). These nanoporous carbons have been investigated as electrodes in electrochemical applications.

A simple carbonization procedure is proposed for the synthesis of hierarchical nanoporous carbons with controllable pore size and effective surface area as electrode materials for high-performance electrochemical double-layer capacitors. The procedure is based on the carbonization of interpenetrating polymer networks (IPNs) composed of cross-linked polystyrene (PS) and poly(methyl methacrylate) (PMMA). The as-obtained hierarchical nanoporous carbons (HNC-IPNs) have controllable pore size, interconnected pore structure, high specific surface area, excellent electrical conductivity and electrochemical stability with the different mass ratio of PS/PMMA. In addition, there is authentically an excellent linear relationship between effective specific surface area (E-SSA) and specific capacitance.Especially, the HNC-IPN-4 exhibits the highest specific surface area (SSA) of 1346 m 2 g À1, relative high E-SSA of 603 m 2 g À1 , and excellent specific capacitance of 260 F g À1 under the current density of 0.5 A g À1 in 6 M KOH. Meanwhile, the HNC-IPN-4 exhibits a superior cycling performance without any degradation after 10 000 cycles with the current density of 2 A g À1 as well as exhibits high capacitance retention, i.e., 96.0% of the initial specific capacitance after 20 000 cycles.
