Microporous 3D graphitic carbons obtained by soft templating as carbocatalysts for aerobic oxidation

Hierarchical Phenolic Resin-based Carbons with High Surface Area and Pore Volume Obtained by Soft-templating and Activation

Introduction Advanced applications often require carbons with high surface area and hierarchical porous structures. In response to this demand some efforts have been undertaken to create materials, which effectively combine the properties of both activated carbons (high surface area) and ordered mesoporous carbons (tunable and well-developed porosity). While there are activation methods, which ...

Mesoporous C/CrN and C/VN Nanocomposites Obtained by One-Pot Soft-Templating Process

Nanocomposites of ordered mesoporous carbon associated with chromium nitride (CrN) or vanadium nitride (VN) nanoparticles were obtained by a simple one-pot synthesis based on the solvent evaporation induced self-assembly (EISA) process using Pluronic triblock surfactant as soft-template and a phenol-based resin (resol) as carbon precursor. These nanocomposites were characterized by X-ray diffra...

Nitrogen-Rich Polyacrylonitrile-Based Graphitic Carbons for Hydrogen Peroxide Sensing

Catalytic substrate, which is devoid of expensive noble metals and enzymes for hydrogen peroxide (H₂O₂), reduction reactions can be obtained via nitrogen doping of graphite. Here, we report a facile fabrication method for obtaining such nitrogen doped graphitized carbon using polyacrylonitrile (PAN) mats and its use in H₂O₂ sensing. A high degree of graphitization was obtained with a mechanical...

Hydrothermal synthesis of microalgae-derived microporous carbons for electrochemical capacitors

Soft materials with graphitic nanostructures.

This review article focuses on our recent studies on novel soft materials consisting of carbon nanotubes. Single-walled carbon nanotubes, when suspended in imidazolium ion-based ionic liquids and ground in an agate mortar, form physical gels (bucky gels), where heavily entangled bundles of carbon nanotubes are exfoliated to give highly dispersed, much finer bundles. By using bucky gels, the fir...
