Book Description
In this study, a suite of novel CO2 capture sorbents were prepared employing three facile synthetic routes: amine assimilation (co-synthesis), wet impregnation and in situ-impregnation synthesis, to develop a range of materials capable of efficiently adsorbing CO2 while demonstrating their applicability as alternative materials for CO2 capture from coal and gas fired power plants via post-combustion carbon capture. Prepared sorbents were characterised for individual physical and chemical properties, using, scanning electron microscopy, infrared spectroscopy, thermogravimetric analysis, elemental analyses and N2 sorption at 77 K. CO2capture capacities were determined using gravimetric analysis under a range of analysis conditions (different temperature and pressure), with the corresponding effects of materials characteristics on CO2 capacities investigated. The effect of amine incorporation was explored in detail, with findings first bench-marked against the corresponding amine free counterparts, and, then, the effect of increasing amine content analysed. So far, within the context of this study, results suggest that materials prepared via the synthetic routes adopted, exhibit high degrees of synthetic control; in addition, CO2 capture capacities were determined to be dependent upon both textural properties but, more importantly, the basic nitrogen functionalities contained within these materials. This observation was prominent with amine in-situ impregnated silica and melamine resorcinol formaldehyde samples, but not wholly for bio-inspired amine silica samples, as the degree of amine functionalisation could not be controlled by the synthetic route chosen. Irrespective, all materials have shown enhanced adsorption performance as a result of the incorporation of basic nitrogen functionalities into the sorbent structures. Furthermore, prepared materials exhibited easy regeneration and maintained stable sorption capacities ≤ 99.9% over the cycles analysed, with results obtained suggesting new strategies for carbon capture materials development for efficient CO2 capture from power plant flue gas and other relevant applications.

Book Description
The use of novel hyperbranched aminosilica (HAS) materials created through the ring-opening polymerization of aziridine from mesoporous silica supports was proposed for the adsorption of CO2 from dilute sources. The limits of the adsorptive performance of these adsorbents were investigated via the preparation of sets of materials with a range of aminopolymer loadings on several different silica supports with different pore space characteristics. Relationships were determined between the materials' amine loadings and the CO2 adsorption performance. Adsorbents with substantial remaining pore volume displayed universal adsorption kinetics when normalized by amine loading. However, materials with blocked pores displayed substantially slower adsorption kinetics due to hindered mass transfer. In both humid and dry conditions, the HAS adsorbent was found to have a surprisingly large CO2 capacity in light of the 250-fold reduction in CO2 partial pressure from 10% CO2 (flue gas application) to 400 ppm CO2 (air capture application). : Finally, a new series of linear aminosilicas was created through the reaction of existing aminosilicas with N-protected-aziridines. Specifically, reaction of aminosilane-functionalized silicas with N-methylaziridine resulted in the linear growth of methylaminoethyl groups, effectively increasing the amine loading of the adsorbent by a stoichiometric amount of an additional amine per attached silane.

Book Description
Metal-Organic Framework Materials (MOFs) are well suited for absorbing carbon dioxide. MOFs can form highly-porous structures with great adsorption capacities. They also offer good catalytic properties and much research refers to the relationship between catalytic performance and framework structure. In addition to simple CO2 absorption, there are other interesting applications, such as the direct electrochemical reduction into useful chemicals and fuels, the conversion of CO2 into methanol, the electrochemical reduction of CO2, or electrocatalytic hydrogen evolution (thus boosting the ‘hydrogen economy’). The book references 295 original resources and includes their direct web link for in-depth reading. Keywords: Global Warming, Carbon Dioxide Capture, Metal-Organic Frameworks MOFs, Adsorbents for CO2, Porous Solids, Catalytic Performance, Synthesis of MOFs, Conversion of CO2 into Methanol, Electrocatalytic Hydrogen Evolution, Hydrogen Economy, Gas Adsorption, Gas Separation, Organic Ligands, Metal Ion Clusters.

Book Description
Following in the lineage of Adsorption by Carbons (Bottani & Tascon, 2008), this work explores current research within contemporary novel carbon adsorbents. Both basic and applied aspects are discussed for this important class of materials. The first section of the book introduces physical adsorption and carbonaceous materials, and is followed by a section concerning the fundamentals of adsorption by carbons. This leads to development of a series of theoretical concepts that serve as an introduction to the following section in which adsorption is mainly envisaged as a tool to characterize the porous texture and surface chemistry of carbons. Particular attention is paid to novel nanocarbons, and the electrochemistry of adsorption by carbons is also addressed. Finally, several important technological applications of gas and liquid adsorption by carbons in areas such as environmental protection and energy storage constitute the last section of the book. - Encompasses fundamental science of adsorption by carbons, in one location, supporting current R&D without extensive literature review - Describes adsorption as it is currently applied to major novel types of carbon materials, including carbon gels, carbide-derived carbons, zeolite-templated carbvons, hydrothermal carbons, carbon nanohorns and graphene - Specific discussion of fuel storage, environmental remediation and biomedical applications, of contemporary interest to many surface chemists and applications-focused researchers
