Aqueous dye adsorption on ordered mesoporous carbons

Journal of Colloid and Interface Science, 2007
Ordered mesoporous carbons (OMCs) with varying pore size, and microporous carbon, CFY, were synthesized using ordered mesoporous silica SBA-15 and NaY zeolite as hard templates, respectively. N(2) adsorption tests show that the synthesized OMCs possess abundant mesopores and centralized mesopore distribution.

Incorporation of platinum nanoparticles in ordered mesoporous carbon

Journal of Colloid and Interface Science, 2007
Platinum nanoparticles were incorporated within the pore system of ordered mesoporous carbon (OMC) by impregnating the carbon with a water-in-oil (w/o) microemulsion containing dissolved platinum salt followed by reduction of the platinum ions in situ inside the carbon pore system.

Ordered mesoporous carbon for electrochemical sensing: A review

Analytica Chimica Acta, 2012
With its well-ordered pore structure, high specific surface area and tunable pore diameters in the mesopore range, ordered mesoporous carbon (OMC) is suitable for applications in catalysis and sensing. We report recent applications of OMC in electrochemical sensors and biosensors.

Aminated hydrophilic ordered mesoporous carbons

Journal of Materials Chemistry, 2007
This paper describes a single step procedure by which primary amine groups are anchored onto ordered mesoporous carbon in a one step reaction. Ordered carbon materials with functional groups residing at the pore surface are prepared using SBA-15 silica as template in combination with hydrothermal carbonisation at mild temperatures (180 °C).

Surface chemistry of ordered mesoporous carbons

Carbon, 2002
Abstract Ordered mesoporous carbons (OMC) were produced by pyrolysis of hydrocarbons adsorbed in two different silica matrices (MCM-48 and SBA-15), followed by dissolution of the matrix in either hydrofluoric acid or sodium hydroxide. Some carbons were subsequently heat treated at temperatures of up to 1600 °C.

NaAlH4 confined in ordered mesoporous carbon

International Journal of Hydrogen Energy, 2013
Abstract In this paper we performed a comprehensive investigation of the structural and sorption properties of a 40 wt. % NaAlH4 confined in a ordered mesoporous carbon (OMC, i.e. CMK-3) by means of X-ray diffraction (XRD), transmission electron microscopy (TEM), 23Na{1H} and 27Al{1H} solid-state magic angle spinning-nuclear magnetic resonance (MAS ...

Ordered mesoporous carbon particles covered with carbon nanotubes

Carbon, 2006
The preparation of carbon nanostructure, namely ordered mesoporous carbon (OMC) covered with carbon nanotubes (CNT) was described. The CNTs on the external surface of the OMC were found to form an interconnected network, which facilitates electron transport between the OMC particles. It was shown that the presence of CNTs on the external surface of OMC

Synthesis of Mesoporous Carbons Using Ordered and Disordered Mesoporous Silica Templates and Polyacrylonitrile as Carbon Precursor

The Journal of Physical Chemistry B, 2005
Mesoporous carbons were synthesized from polyacrylonitrile (PAN) using ordered and disordered mesoporous silica templates and were characterized using transmission electron microscopy (TEM), powder X-ray diffraction, nitrogen adsorption, and thermogravimetry.

Ordered mesoporous carbon/α-alumina nanosheet composites

Nanoscale, 2010
Novel α-alumina crystalline nanosheets are used for the preparation of alumina-carbon composites, in which the latter component is phenolic resin-based ordered mesoporous carbon. A unique feature of these composites is perpendicular orientation of ordered mesopores of the carbon to the (001) facets of nonporous α-alumina nanosheets accompanied by ...
