3D N-doped ordered mesoporous carbon supported single-atom Fe-N-C catalysts with superior performance for oxygen reduction reaction and zinc-air battery

, 2021
Single-atom Fe-N-C electrocatalysts have emerged as the most promising oxygen reduction reaction (ORR) catalyst. However, the low Fe loading and inaccessibility of Fe-N-C sites limit the overall ORR activity.

Hollow mesoporous carbon nanospheres space-confining ultrathin nanosheets superstructures for efficient capacitive deionization.

Journal of Colloid and Interface Science, 2022
In this work, we propose a novel strategy to fabricate nickel silicate nanoflakes inside hollow mesoporous carbon spheres (Ni3Si2O5(OH)4/C). Hollow mesoporous carbon spheres (HMCSs) can well regulate and limit the growth of Ni3Si2O5(OH)4 nanosheets ...

Yolk-shelled Co@SiO2@Mesoporous carbon microspheres: Construction of multiple heterogeneous interfaces for wide-bandwidth microwave absorption.

Journal of Colloid and Interface Science, 2021
Nowadays, in the practical application of microwave absorption, it is still urgent and challenging to develop the microwave absorber with broadened bandwidth at a single thickness. Constructing composites with multi-component and multi-structure has been

Mesoporous Carbon Materials: Synthesis and Modification

Angewandte Chemie - International Edition, 2008
AbstractPorous carbon materials are of interest in many applications because of their high surface area and physicochemical properties. Conventional syntheses can only produce randomly porous materials, with little control over the pore‐size distributions, let alone mesostructures.

Removal of AV 90 dye using ordered mesoporous carbon materials prepared via nanocasting of KIT-6: Adsorption isotherms, kinetics and thermodynamic analysis

, 2021
CMK-8 type ordered mesoporous carbon (OMC) materials were prepared by hard-templating method using KIT-6 as a mesoporous silica template. The influence of synthesis parameters in the structural properties of KIT-6 and OMC materials were investigated.

Mesoporous Activated Carbon Filaments

MRS Proceedings, 1996
ABSTRACTActivated carbon filaments of diameter ∼0.1 μm, main pore size (BJH) 55 Å, specific surface area 1310 m2/g and yield 36.2% were obtained by activating carbon filaments of diameter ∼ 0.1 urn in C02 + N2 (1:1) at 970°C for 80 min. Prior to this activation, the filaments were surface oxidized by exposure to ozone.

Application of mesoporous carbon and modified mesoporous carbon for treatment of DMF sewage

Journal of Nanoparticle Research, 2016
Mesoporous carbon (MC) was prepared in soft template, and potassium ferricyanide was added into MC to prepare the modified mesoporous carbon (MMC). TEM, SEM, FT-IR, and N2 adsorption–desorption were used to characterize the textural properties of mesoporous materials.

Ordered Mesoporous Carbons

Advanced Materials, 2001
Ordered mesoporous carbons have recently been synthesized using ordered mesoporous silica templates. The synthesis procedure involves infiltration of the pores of the template with appropriate carbon precursor, its carbonization, and subsequent template removal.
