چکیده مقاله:

Ordered Mesoporous Carbon (OMC) represents an interesting material for electric double layer capacitors which has the high surface area, easily accessed ordered pore channels and lower production cost. In this work, CMK-3 as promising OMC has been fabricated using the ordered mesoporous silica SBA-15 as a template. The structure and morphology of CMK-3 are characterized by X-ray diffraction, nitrogen adsorption/desorption, and scanning electron microscopy. CMK-3 is sprayed on the surface of highly conductive three-dimensional nickel foam and characterized as an electrode for electric double layer capacitors. When this electrode is soaked in a neutral aqueous electrolyte solution, reaches a specific capacitance as high as 285 and 167 F/g, at a current density of 10 and 34 A/g, respectively. CMK-3 shows excellent long-term stability with >90% capacitance retention after 10000 cycles, as well as high power (37 kW/kg) and energy density (98 Wh/kg).

Significant Performance Enhancement in Asymmetric Supercapacitors based on Metal Oxides, Carbon nanotubes and Neutral Aqueous Electrolyte

Amongst the materials being investigated for supercapacitor electrodes, carbon based materials are most investigated. However, pure carbon materials suffer from inherent physical processes which limit the maximum specific energy and power that can be achieved in an energy storage device. Therefore, use of carbon-based composites with suitable nano-materials is attaining prominence. The synergis...

Ordered nanoporous carbon (CMK-3) coated fiber for solid-phase microextraction of benzene and chlorobenzenes in water samples

Nanoporous carbons (CMK-3) were prepared and have been used as a fiber coating for headspace solid phase microextraction (HS-SPME). The prepared materials were characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and N2 adsorption/desorption isotherms. The efficiency of the fiber was evaluated using a gas chromatography (GC) system for the extraction of benzene (B) and c...
