Synthesis of mesoporous carbons using silica templates impregnated with mineral acids

Facile synthesis of hierarchically porous carbonaceous materials derived from olefin/aldehyde precursors using silica as templates

“…By the way, growing deformation of the ordered mesoporous structure was formed with the increase of incorporated P 2 O 5 content, as it has been reported in the literature. 16 Additionally, various P-containing samples have been also characterized by N 2 adsorption. The corresponding N 2 adsorption isotherms and pore size distribution are displayed in Fig.…”

“…13 In the synthesis, various organic compounds introduced by either wet impregnation or chemical vapour deposition (CVD) were normally carbonized using porous silicas as sacricial scaffolds for the replication of porous carbon materials with controlled structures. [14][15][16] In general, organic compounds, such as sucrose, furfuryl alcohol, phenol resin, and acrylonitrile, can be used as carbon sources, 8 the key to nanocasting approach lies in the polymerization of organic feeds inside the mesoporous silica channels, which is achieved by the incorporation of an acid into the silica template before converted to mesoporous carbon by pyrolysis. 17 Therefore, the successful synthesis of mesoporous carbon through this method relys on the impregnated organic source lling the entire pore and retain the rigid matrix aer chemical etching by hydrouoric acid (HF) or a sodium hydroxide solution.…”

Impregnation Nickel on Mesoporous ZSM-5 Templated Carbons as a Candidate Material for Hydrogen Storage

“…A couple of carbon based hydrogen storing materials prepared by using porous materials template like zeolite Y, β, L, 13X as well as SBA-15, SBA-16 and KIT-6 mesoporous silica have been widely reported [2][3]. But taking advantage of a mesoporous ZSM-5 zeolite as a carbon template has not been much reported, therefore it is very interesting to study the material characteristics and its H 2 uptake capabilities from mesoporous carbon with ZSM-5 mesoporous template.…”

Precise construction on the structure of zeolite microcapsules

“…It could be concluded that the micro@meso core-shell structure has attracted more and more researchers due to its specific characters and structures. Another member in the mesoporous family is the porous carbon [22] with mesopores (2-50 nm) inside. Owing to its peculiar features such as the resistance to the acid or the alkalinity, the flexibility of the pore size and the large surface area [23][24][25][26], the mesoporous carbon has been widely used as an excellent support for the catalytic processes and electronic applications [27][28][29][30].…”
