Mesoporous silica hybridized by ordered mesoporous carbon for in‐tube solid‐phase microextraction
Journal of Separation Science, 2020AbstractTo enhance the extraction performance, a mesoporous silica was modified with ordered mesoporous carbon for solid‐phase microextraction. Three stainless‐steel wires coated with the mesoporous material were placed in a polyetheretherketone tube for getting an extraction tube.

Efficient synthesis and sulfonation of ordered mesoporous carbon materials
Journal of Colloid and Interface Science, 2012Ordered mesoporous carbons (OMCs) with hexagonal structure were efficiently synthesized via cooperative self-assembly of phenol/formaldehyde resol and surfactant F127 under acidic aqueous conditions. Induced by HCl, a gel phase mainly containing phenol/formaldehyde resol and F127 was obtained within several hours.

The Journal of Physical Chemistry C, 2007
The synthesis and characterization of amorphous N-incorporated carbon materials, with ordered mesoporous structure, using mesoporous aluminosilicate oxynitride (OMASON) as a solid template for the first time is reported. The use of furfuryl alcohol (FA) as carbon precursor generates the N-incorporated mesoporous carbon material with nitrogen contents ...

Rapid removal of bisphenol A on highly ordered mesoporous carbon
Journal of Environmental Sciences, 2011Bisphenol A (BPA) is of global concern due to its disruption of endocrine systems and ubiquity in the aquatic environment. It is important, therefore, that efforts are made to remove it from the aqueous phase. A novel adsorbent, mesoporous carbon CMK-3, prepared from hexagonal SBA-15 mesoporous silica was studied for BPA removal from aqueous phase, and

Mesopore-Aspect-Ratio Dependence of Ion Transport in Rodtype Ordered Mesoporous Carbon
The Journal of Physical Chemistry C, 2008The ion transport behavior in hexagonal ordered mesoporous carbon (OMC, two-dimensional mesopore symmetry) materials with diverse mesopore diameter and length was studied by evaluating the dynamic process of inner-pore electric double layer formation.

Ordered Mesoporous Carbon as an Efficient and Reversible Adsorbent for the Adsorption of Fullerenes
Langmuir, 2006An ordered mesoporous carbon, CMK-3, was synthesized using a mesoporous siliceous material, SBA-15, as the template. CMK-3 was characterized and used for the adsorption of fullerenes C60 and C70. It was found that the adsorption capacity of CMK-3 is 4 times higher than that of activated carbon. The adsorption equilibrium isotherms of C60 and C70 on CMK-

Ordered Mesoporous Carbons as Catalyst Support for PEM Fuel Cells
Fuel Cells, 2009AbstractPreliminary results on Pt‐based electrocatalysts prepared with CMK3 mesoporous carbons are presented. The electro‐catalytic performance towards the oxygen reduction reaction (ORR) was compared to that of commercial Pt/C‐Vulcan catalysts with the same Pt content.

The effect of high temperature treatment of ordered mesoporous carbons (OMCs) under neutral atmosphere is studied for OMCs prepared by using different carbon precursors (furfuryl alcohol, sucrose, acenaphthene and mesophase pitch) and different ordered mesoporous silica (OMS) templates (MCM-48 and KIT-6).

Templating synthesis of ordered mesoporous carbon particles
Carbon, 2005This research reports the synthesis of spherical ordered mesoporous carbon particles using mesoporous silica particles as a template. The silica particles with ordered cubic and lamellar mesostructures were synthesized from an aerosol-assisted self-assembly process using block copolymer surfactants as the structural directing agent.
