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. The book presents a short history of each technique and material, and assesses advantages and disadvantages. This focused book provides researchers with a comprehensive understanding of both pioneering and current synthesis techniques for porous carbons, and their modern applications. Presents modern porous carbon synthesis techniques and modern applications of porous carbons Presents current research on porous carbons in energy storage, conversion and adsorption, and in environmental remediation Provides a history and assessment of both pioneering and current cutting-edge synthesis techniques and materials Covers a significant range of precursor materials, preparation techniques, and characteristics Considers the future development of porous carbons and their various potential applications

Porous carbon materials are at the heart of many applications, including renewable energy storage and generation, due to their superior physical properties and availability. The environmentally-friendly production of these materials is crucial for a sustainable future. This book focuses on the transformation of sustainable precursors into functional, porous carbonaceous materials via the two most significant approaches: Starbon® and Hydrothermal Carbonisation. Covering cutting-edge research and emerging areas, chapters cover applications of porous carbon materials in catalysis and separation science as well as in energy science. Moreover, the challenges of characterization of these materials and their commercialization are explained by worldwide experts. The content will be accessible and valuable to post-graduate students and senior researchers alike and it will serve as a significant reference for academics and industrialists working in the areas of materials science, catalysis and separation science.

This research is aimed at developing novel, porous activated carbon materials that are used for CO2 capture. The research is mainly composed of two parts: synthesis, characterization of novel porous carbons produced via KOH activation; and evaluation of their preliminary CO2 capture performances. Various kinds of porous carbons were synthesized via KOH activation method. Through activation of multi-wall carbon nanotubes, the mechanism of pore formation was proposed. This understanding of the pore-forming mechanism also provides a good platform to investigate the effect of absorbent's pore structures on its CO2 capture behavior. This study demonstrated the significant role of pore sizes less than 1 nm in the physisorption of CO2 molecules. Furthermore, activated carbons with ultrahigh surface area were synthesized by KOH activation of polyaniline. By studying the effect of the preheating stage, it was determined that formation of network-like nanostructure at preheating stage of the activation process is beneficial to the pore development and can lead to activated carbons with exceptionally high surface area. It is believed that this mechanism could be applied to the activation of other carbon precursors in order to achieve improved specific surface area (SSA) and micropore volume. The evaluation of the CO2 capture performances were conducted for two novel activated carbons: porous carbons derived from a liquid carbon precursor (polyethylenimine), and LiCl-incorporated activated carbons. For the porous carbons derived from polyethylenimine, they possess microporosity and rich nitrogen content. At 1 bar the CO2 uptake of the carbons was 4.9-5.7 mmol g-1 at 0 oC. These carbons also demonstrated a selectivity of 33 for CO2 over N2 at 25 oC and less than 1% decrease of the performance after 30 cycles. For LiCl-incorporated porous carbons, the CO2 adsorption capacity decreased after LiCl incorporation, mainly because of blocking of the small micropores. However, the increase of initial Qst after LiCl incorporation indicated a positive role of LiCl in terms of CO2 interaction with sorbent surfaces.

The series Advances in Polymer Science presents critical reviews of the present and future trends in polymer and biopolymer science. It covers all areas of research in polymer and biopolymer science including chemistry, physical chemistry, physics, material science. The thematic volumes are addressed to scientists, whether at universities or in industry, who wish to keep abreast of the important advances in the covered topics. Advances in Polymer Science enjoy a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic, and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles, and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist. Review articles for the individual volumes are invited by the volume editors. Single contributions can be specially commissioned. Readership: Polymer scientists, or scientists in related fields interested in polymer and biopolymer science, at universities or in industry, graduate students.
