Hydrophilicity-Controlled Ordered Mesoporous Carbon for Lithium-Sulfur Batteries

Journal of Nanoscience and Nanotechnology, 2014
Ordered mesoporous carbon (OMC) materials were synthesized from a mesoporous silica KIT-6 (3-D cubic la3d meso-structure) as the hard-template via a nano-replication method. Hydrophilic and hydrophobic OMC materials were prepared using different carbon precursors including sucrose (suc-OMC) and phenanthrene (phe-OMC) at different carbonization ...

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).

Mesoporous silica hybridized by ordered mesoporous carbon for in‐tube solid‐phase microextraction

Journal of Separation Science, 2020
AbstractTo 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.

Highly Uniform Carbon Sheets with Orientation-Adjustable Ordered Mesopores

ACS Nano, 2018
A soft-hard template-assisted method toward the unconventional free-standing ordered mesoporous carbon sheets (OMCSs) with uniform hexagonal morphology is developed by applying MgAl-layered double hydroxide (MgAl-LDH) as the hard template, triblock copolymer F127 as the soft template, and phenolic resols as the carbon sources.

Efficient synthesis and sulfonation of ordered mesoporous carbon materials

Journal of Colloid and Interface Science, 2012
Ordered 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.

Highly ordered mesoporous carbons-based glucose/O2 biofuel cell

Biosensors and Bioelectronics, 2009
This study demonstrates a novel compartment-less glucose/O(2) biofuel cell (BFC) based on highly ordered mesoporous carbons (OMCs) with three-dimensionally (3D) interconnected and ordered pore structures. OMCs are used as supports for both stably confining the electrocatalyst (i.e., meldola's blue, MDB) for NADH oxidation and the anodic biocatalyst (i ...

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 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 Electrodes for Li–O2 Batteries

ACS Applied Materials & Interfaces, 2013
Ordered mesoporous carbon (OMC) with highly ordered pore channels was applied as an oxygen-side electrode for a Li-O2 battery. To evaluate the effect of the pore channel size on battery performance, we employed OMCs possessing two different pore sizes (6 and 17 nm).

Electrochemical determination of morphine at ordered mesoporous carbon modified glassy carbon electrode

Biosensors and Bioelectronics, 2010
A sensitive electrochemical detection scheme for morphine has been proposed by utilizing the ordered mesoporous carbon modified glassy carbon electrode (OMC/GCE). The electrochemical behaviour of morphine at the OMC/GCE was investigated by cyclic voltammetry. The modified electrode displayed a decrease in the overpotential (ca.
