Rapid removal of bisphenol A on highly ordered mesoporous carbon

Journal of Environmental Sciences, 2011
Bisphenol 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

Bicontinuous mesoporous carbon thin films via an order–order transition

Chem. Commun., 2014
Fabrication of mesoporous carbon films with gyroid morphology using soft templating with resol is sensitive to exact details of solvent processing, thermal annealing and the age of the resol.

Mesopore-Aspect-Ratio Dependence of Ion Transport in Rodtype Ordered Mesoporous Carbon

The Journal of Physical Chemistry C, 2008
The 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 Carbons as Catalyst Support for PEM Fuel Cells

Fuel Cells, 2009
AbstractPreliminary 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.

Ordered Mesoporous Carbon as an Efficient and Reversible Adsorbent for the Adsorption of Fullerenes

Langmuir, 2006
An 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-

High temperature treatment of ordered mesoporous carbons prepared by using various carbon precursors and ordered mesoporous silica templates

New Journal of Chemistry, 2008
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).

Ordered Mesoporous Carbon/Fused Silica Composites

Advanced Functional Materials, 2008
AbstractA series of novel, dense, and interesting ordered mesoporous carbon (OMC)/fused silica composites with different carbon contents has been prepared by a controllable but simple sol‐gel method followed by hot‐pressing. In the as‐sintered OMC/fused silica composites the carbon particles still exist in the form of perfectly ordered carbon nanowires.

Templating synthesis of ordered mesoporous carbon particles

Carbon, 2005
This 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.

A Facile Way to Synthesize Ordered Mesoporous Carbon Replicated by Mesoporous Silicas

Solid State Phenomena, 2007
High ordered mesoporous carbon molecular sieves designated as CMK-3 and CMK-5 was synthesized using mesoporous silica SBA-15 as hard template, pre-polymerized furfuryl alcohol as a carbon souse by one-step impregnation. The effect of the furfuryl alcohol to silicas ratio have been investigated.

A simple method for synthesis of ordered mesoporous carbon

Diamond and Related Materials, 2019
Abstract A series of ordered mesoporous carbons (OMCs) was synthesized via a simple method using a nonionic surfactant (block copolymer) P123 both as a structure–directing agent and as a carbon precursor at different carbonization temperatures (500 °C, 600 °C, 700 °C, and 800 °C).
