Ordered mesoporous carbon catalyst for dehydrogenation of propane to propylene
Chemical Communications, 2011Metal-free ordered mesoporous carbons were demonstrated to be robust catalysts for direct dehydrogenation of propane to propylene, in the absence of any auxiliary steam, exhibiting high activity and selectivity, as well as long catalytic stability, in comparison with nanostructured carbons.

Ordered mesoporous carbon (OMC) and metal-doped (M-doped) OMC composites are prepared, and their electromagnetic (EM) parameters are measured. Using the measured EM parameters we calculate the EM wave absorption properties of a double-layer absorber, which is composed of OMC as an absorbing layer and M-doped OMC as the matching layer.

Preparation of Activated Ordered Mesoporous Carbons with a Channel Structure
Langmuir, 2008Activated ordered mesoporous carbons with a channel structure (AOMCs-CS) were successfully prepared by imposing CO(2) activation on ordered mesopore carbon C-FDU-15. It is found that the continuous carbon framework of the precursor C-FDU-15 plays an important role in keeping the order structure of the resulting AOMCs-CS.

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-
