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 ...

Preparation of ordered mesoporous crystalline alumina replicated by mesoporous carbon

Microporous and Mesoporous Materials, 2008
Abstract Ordered mesoporous alumina with crystalline framework walls has been fabricated using a repeated nanocasting strategy. Mesoporous silica and mesoporous carbon were successively employed as the exotemplates. Constrained by the rigid carbon template structure, the alumina precursor in the channels of the carbon template could be well ...

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 ...

Ordered mesoporous carbon catalyst for dehydrogenation of propane to propylene

Chemical Communications, 2011
Metal-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.

Enhanced absorption properties of ordered mesoporous carbon/Co-doped ordered mesoporous carbon double-layer absorbers

Chinese Physics B, 2013
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, 2008
Activated 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.
