“…The silica was impregnated at 575 K with petroleum pitch 'Ashland A240' during 4 hours. The mixture was then heated under Argon up to 1225 K at 3 K/min to convert the pitch into carbon (Vix-Guterl et al, 2002, 2003Parmentier et al, 2004). CS15 and CS48.…”

“…During the last five years, several synthesis routes of ordered mesoporous carbons by replication from silica templates have been presented (Ryoo et al, 1999;Vix-Guterl et al, 2002;Vix-Guterl et al, 2003;Parmentier et al, 2004). These materials have numerous properties which may be of interest, such as a microporous volume which can be large and the presence of a three dimensional mesoporous network which enhance the dynamics of diffusion in the material.…”

The adsorption of hydrogen on nanostructured carbons prepared by templating of mesoporous silicas has been studied at 77 K and between 0.1 and 1 MPa. The maximum capacity was obtained with a carbon synthetized by a sucrose liquid infiltration process in MCM-48 silica. It was observed that the hydrogen weight percentage which can be adsorbed on a carbon can be correlated to its microporous volume determined by CO 2 adsorption and Dubinin-Radushkevich equation.

“…MPs are derived from polyaromatic systems and generally form polydomain liquid crystals constructed by well-stacking layers of carbon rings. The n-n stacking between the molecular units of MPs keeps the incorporating process in a continuous fashion, leading to a perfect packing of MPs in the pores (96,99,100). Etching the silica results in a true replica of the 3D bicontinuous cubic mesostructure (laZd) with the complicated graphitized orientation (Figure 17).…”

The design of ordered nonsiliceous mesoporous materials is illustrated based on the surfactant assembly and confinedspace growth. These materials include mesoporous metal oxides, polymers, and carbons with open framework structures, and single-crystal metal, metal oxide and carbon nanoarrays with replicated mesostructures. A generalized "acid-base pair" concept, which self-adjusts the acidity and homogeneity of the inorganic precursor, is proposed to prepare highly ordered mesoporous metal oxides, phosphates and borates, as well as mixed metal oxides and phosphates, with diverse structures. Mesoscopically ordered polymer frameworks with uniformly large pore sizes are derived from the self-assembly from organic templates and organic precursors. Heating these materials transforms them to homologous carbon frameworks. Microwave digested method is an efficient way to enhance the adsorption property of hard silica templates in fabricating ordered nonsiliceous single-crystal nanoarrays. The coordination of organic surfactants with metal ions is also a method to increase the interaction between hard templates and precursors. A one-step impregnation process is used to fabricate ordered silica monoliths with various metal oxide nanocrystals. Improving the interactions between the precursors themselves plays an essential role in replicating ordered mesoporous CdS, SiC and graphitized carbons. Preliminary applications in bone-forming materials, biosensors and electrodes are presented as well.

“…The development of new porous carbons has become possible these last years by using a templating approach [1][2][3][4][5][6][7]. The method is based on the filling of the organized porous structure of a silica host by a carbon precursor in gaseous or liquid phase followed, if necessary, by a carbonization.…”
