Preparation of model mesoporous carbons

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1988
The objective of this work was to prepare mesoporous carbon solids made of monosized spherical particles, produced from poly(acrylonitrile)(PAN) precursors, after oxidation in air and subsequent carbonization under an inert atmosphere. The precursors were obtained from PAN latices by slow drying in air.

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).

Mesoporous carbon nitrides: synthesis, functionalization, and applications

Chemical Society Reviews, 2017
Mesoporous carbon nitrides (MCNs) with large surface areas and tuneable pore diameters are unique semiconducting materials and exhibit excellent physicochemical properties, which promote their application in diverse fields including photocatalysis, sensing, and energy storage and conversion.

Vanadium-containing mesoporous carbon and mesoporous carbon nanoparticles as catalysts for benzene hydroxylation reaction

Materials Today Communications, 2017
Abstract Highly ordered mesoporous carbon of body-centered cubic structure was synthesized by the evaporation induced self-assembly method using Pluronic F127 and phenolic resol as the template and carbon source, respectively. Vanadium species were introduced to the carbon support by both co-assembly and impregnation strategies for comparison ...

Self-Assembly for Mesoporous Carbon

2017
This chapter describes the self-assembly process for the mesoporous carbons (MC) prepared using soft and hard templates. Design and modification of MC mainly depends on the templates which are prepared via the self-assembly of inorganic and organic molecules. These self-assembly processes play an important role in controlling the structure, morphology,

Molecular-Sieving Capabilities of Mesoporous Carbon Membranes

The Journal of Physical Chemistry B, 2008
The size-sieving properties of a mesoporous carbon membrane were studied via molecular permeation and cyclic voltammetry experiments. Two phenomena, simple diffusion and electrochemically aided diffusion, were investigated. Molecular diffusion through the membrane was caused by a concentration gradient across the membrane and was facilitated by ...

Surface chemistry of carbon-templated mesoporous aluminas

Physical Chemistry Chemical Physics, 2009
Using infrared spectroscopy, a comparative investigation was carried out of the surface properties of mesoporous aluminas prepared by the carbon templating route and of a commercial alumina PURAL SB. In the hydroxylated state the mesoporous materials bear surface OH groups terminally bonded to an octahedral Al3+ ion, which has basic properties.

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 ...

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.

Adsorption of alkaloids on ordered mesoporous carbon

Journal of Colloid and Interface Science, 2013
An ordered mesoporous carbon (OMC) adsorbent was synthesized, characterized, and evaluated for effective separation and purification of alkaloid compounds from aqueous solutions. The OMC adsorbent has a large BET specific surface area (1532.2m(2)/g), large pore volume (2.13cm(3)/g), and narrow pore diameter distribution with a median pore diameter of 4.
