“…They could show that the pore size did not shrink but instead increased due to a strong adhesion to the alumina walls during carbonization. An alternative macroporous template was recently introduced by Liu et al [27] Here a calcined crab shell was used as hard template, which consists of CaCO 3 with disordered pores of 70 nm in diameter.…”

Cubic and circular hexagonal mesoporous carbon phases in the confined environment of the pores of anodic alumina membranes (AAM) were obtained by organic-organic self-assembly of a preformed oligomeric resol precursor and the triblock copolymer templates Pluronic F127 or P123, respectively. Casting and solvent evaporation were followed by self-assembly and the formation of a condensed wall material by thermopolymerization of the precursor oligomers, thus resulting in mesostructured phenolic resin phases. Subsequent thermal decomposition of the surfactant and carbonization were achieved through thermal treatment at temperatures up to 1000 °C under an inert atmosphere. The resulting hierarchical mesoporous composite materials were characterized by small-angle X-ray scattering and nitrogen-sorption measurements. The structural features were directly imaged in TEM cross-sections of the composite membranes. For both structures, the AAM pores were completely filled and no shrinkage was observed due to strong adhesion of the carbon-wall material to the AAM pore walls. As a consequence, the pore size of the mesophase system stays almost constant even after thermal treatment at 1000 °C.

Mesoporous carbon electrodes have been doped with Co-B nanoparticles via a chemical reduction approach and successfully used for pseudocapacitor application. The morphology is investigated by powder X-ray diffractions (PXRDs), small-angle X-ray scattering (SAXS), inductively coupled plasma (ICP), and transmission electron microscope (TEM). The TEM image displays that the Co-B is highly dispersed along the mesoporous carbon support which are critical for the pseudocapacitor application. Cobalt-boron/ highly ordered mesoporous carbon nanofiber arrays (Co-B/ MCNAs) are investigated by cyclic voltammetry, charge/ discharge test, and electrochemical impedance spectroscopy. The as-synthesized Co-B/MCNAs exhibit remarkable pseudocapacitive activities including high specific capacitance (531 F g −1 at 5 mV s −1 ), good rate capability (315 F g −1 at 50 mV s −1 ), and excellent cycling stability. This value is about 2.7-fold and 1.7-fold higher than MCNAs and Co-B, respectively.

“…At present, activated carbons are widely used as the electric double layer capacitor (EDLC) electrode materials because of their low cost, scalable character and a variety of biomass precursors. Though conventionally activated carbons possess a large surface area, their EDLC performance can be somewhat limited because they actually contain an abundant proportion of micropores not always fully accessible to big ions [12,13]. Therefore, only exposed outer surface are utilized for charge storage.…”

Ordered mesoporous carbons (OMCs) are of great interest in energyrelated research and applications, partly due to their high surface areas, uniform pore channels, and narrow pore size distributions. During the past decades, a number of breakthroughs for the synthesis of OMCs, including hard templating methods and soft templating strategies, have been made by carbon chemists. Thanks to unique properties, OMCs-based supercapacitors are attracting more and more attention around the world in recent years in view of their ultrafast chargedischarge rate, high power capability, low maintenance, and long cycle life. In this chapter, we wish to overview those representative pathways for OMC materials and their performance in supercapacitor application.
