Download or read book Porous Carbons written by Feiyu Kang and published by Elsevier. This book was released on 2021-11-04 with total page 874 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon materials form pores ranging in size and morphology, from micropores of less than 1nm, to macropores of more than 50nm, and from channel-like spaces with homogenous diameters in carbon nanotubes, to round spaces in various fullerene cages, including irregularly-shaped pores in polycrystalline carbon materials. The large quantity and rapid rate of absorption of various molecules made possible by these attributes of carbon materials are now used in the storage of foreign atoms and ions for energy storage, conversion and adsorption, and for environmental remediation. Porous Carbons: Syntheses and Applications focuses on the fabrication and application of porous carbons. It considers fabrication at three scales: micropores, mesopores, and macropores. Carbon foams, sponges, and 3D-structured carbons are detailed. The title presents applications in four key areas: energy storage, energy conversion, energy adsorption, including batteries, supercapacitors, and fuel cells and environmental remediation, emphasizing the importance of pore structures at the three scales, and the diffusion and storage of various ions and molecules.

Download or read book Porosity in Carbons written by John W. Patrick and published by John Wiley & Sons. This book was released on 1995-01-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Porosity in carbons often means different things to different people depending largely on the different applications of the various carbon materials. On the one hand, users involved in gas purification or respiratory protection are concerned primarily with microporosity, and at the other extreme, the user of carbon in the form of metallurgical coke is concerned with macroporosity because of its influence on the mechanical properties of the coke. Between these extremes there is a range of applications which rely on different aspects of the nature of the porous structure and the characterization required reflects the particular application in mind. This characterization of a wide diversity of porous structures presents some problems. However recent developments have produced some solutions, for example computerized image analysis has facilitated the measurement of pore shape and size. The eleven chapters in this book present an analysis of the current methods of characterization and the role of various aspects of carbon porosity in some representative and diverse applications.

Download or read book Heteroatom doped Nanoporous Carbons written by Babak Ashourirad and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated carbons as emerging classes of porous materials have gained tremendous attention because of their versatile applications such as gas storage/separations sorbents, oxygen reduction reaction (ORR) catalysts and supercapacitor electrodes. This diversity originates from fascinating features such as low-cost, lightweight, thermal, chemical and physical stability as well as adjustable textural properties. More interestingly, sole heteroatom or combinations of various elements can be doped into their framework to modify the surface chemistry. Among all dopants, nitrogen as the most frequently used element, induces basicity and charge delocalization into the carbon network and enhances selective adsorption of CO2. Transformation of a task-specific and single source precursor to heteroatom-doped carbon through a one-step activation process is considered a novel and efficient strategy. With these considerations in mind, we developed multiple series of heteroatom doped porous carbons by using nitrogen containing carbon precursors. Benzimidazole-linked polymers (BILP-5), benzimidazole monomer (BI) and azo-linked polymers (ALP-6) were successfully transformed into heteroatom-doped carbons through chemical activation by potassium hydroxide. Alternative activation by zinc chloride and direct heating was also applied to ALP-6. The controlled activation/carbonization process afforded diverse textural properties, adjustable heteroatom doping levels and remarkable gas sorption properties. Nitrogen isotherms at 77 K revealed that micropores dominate the porous structure of carbons. The highest Brunauer-Emett-Teller (BET) surface area (4171 m2g−1) and pore volume (2.3 cm3g−1) were obtained for carbon synthesized by KOH activation of BI at 700°C. In light of the synergistic effect of basic heteroatoms and fine micropores, all carbons exhibit remarkable gas capture and selectivity. Particularly, BI and BIPL-5 derived carbons feature unprecedented CO2 uptakes of 6.2 mmol g−1 (1 bar) and 2.1 mmol g−1 (0.15 bar) at 298 K, respectively. The ALP-6 derived carbons retained considerable amount of nitrogen dopants (up to 14.4 wt%) after heat treatment owing to the presence of more stable nitrogen-nitrogen bonds compared to nitrogen-carbon bonds in BILP-5 and BI precursors. Subsequently, the highest selectivity of 62 for CO2/N2 and 11 for CO2/CH4 were obtained at 298 K for a carbon prepared by KOH activation of ALP-6 at 500°C.

Download or read book Synthesis and Characterization of Activated Carbon Materials for Supercapacitor Applications written by Farshad Barzegar and published by . This book was released on 2015 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unifying theme within this work is the production of porous activated carbon (AC) materials from different carbon-containing precursors for electrochemical supercapacitors (ES) applications. The activated carbon-based ES is an emerging storage technology that promises to play an important role in meeting the rising demands from the energy sector. Thus, it is necessary to study and produce various high-quality ACs by optimizing the micro/meso-porous architecture as electrodes and also study the effect of different electrolytes on the electrochemical behavior of the produced ACs. The produced ACs which are discussed in different sections in chapter 4 show specific surface area ranging from ~300 m2 g-1 to ~3000 m2 g-1, specific capacitances in the range of ~179 F g-1 to ~335 F g-1 and energy density in the range of ~15 Wh kg-1 to ~38 Wh kg-1 at a current density of 0.5 A g. Both symmetric and asymmetric devices also showed excellent long term stability and no capacitance loss after 10,000 charge discharge and the stable operating potential ranging from 1.2 V to 2 V depending on the electrolyte used. All devices kept the important property of supercapacitors which is a high power density even at low current densities. All the results presented above showed the great potential in the adoption of the synthesized activated carbon material for supercapacitor applications.
