Book Description
Offering a materials science point of view, the author covers the theory and practice of adsorption and diffusion applied to gases in microporous crystalline, mesoporous ordered, and micro/mesoporous amorphous materials. Examples used include microporous and mesoporous molecular sieves, amorphous silica, and alumina and active carbons, akaganeites, prussian blue analogues, metal organic frameworks and covalent organic frameworks. The use of single component adsorption, diffusion in the characterization of the adsorbent surface, pore volume, pore size distribution, and the study of the parameters characterizing single component transport processes in porous materials are detailed.

Book Description
Porous materials are of scientific and technological importance because of the presence of voids of controllable dimensions at the atomic, molecular, and nanometer scales, enabling them to discriminate and interact with molecules and clusters. Interestingly the big deal about this class of materials is about the “nothingness” within — the pore space. International Union of Pure and Applied Chemistry (IUPAC) classifies porous materials into three categories — micropores of less than 2 nm in diameter, mesopores between 2 and 50 nm, and macropores of greater than 50 nm. In this book, nanoporous materials are defined as those porous materials with pore diameters less than 100 nm.Over the last decade, there has been an ever increasing interest and research effort in the synthesis, characterization, functionalization, molecular modeling and design of nanoporous materials. The main challenges in research include the fundamental understanding of structure-property relations and tailor-design of nanostructures for specific properties and applications. Research efforts in this field have been driven by the rapid growing emerging applications such as biosensor, drug delivery, gas separation, energy storage and fuel cell technology, nanocatalysis and photonics. These applications offer exciting new opportunities for scientists to develop new strategies and techniques for the synthesis and applications of these materials.This book provides a series of systematic reviews of the recent developments in nanoporous materials. It covers the following topics: (1) synthesis, processing, characterization and property evaluation; (2) functionalization by physical and/or chemical treatments; (3) experimental and computational studies on fundamental properties, such as catalytic effects, transport and adsorption, molecular sieving and biosorption; (4) applications, including photonic devices, catalysis, environmental pollution control, biological molecules separation and isolation, sensors, membranes, hydrogen and energy storage, etc./a

Book Description
The development of metal-organic frameworks (MOFs) have received an increasing attention due to their potential applications for environmental remediation. Because of their ultrahigh micropore volume and large specific surface area, MOFs are specifically applicable for gas adsorption and separation. However, these applications are often limited due to their high cost, restricted mass transfer, and inadequate selectivity. The main objective of this dissertation is the synthesis and characterization of novel nanoporous materials based on ZIF-67 and Cu-BTC MOF frameworks. The first main chapter of this dissertation focuses on the synthesis of small crystals of ZIF-67 using cetyltrimethylammonium bromide (CTAB) surfactant as a capping agent to obtain composites of ZIF-67 and microporous carbon applicable for gas adsorption, including CO2 adsorption. The next chapter focuses on the synthesis of composites consisting of ZIF-67 and gamma alumina (GA) with and without its modification with imidazole-containing silanes. A significant improvement is observed in dye adsorption (Rhodamine B) on the composites as compared to ZIF-67 and GA alone. The composites consisting of GA modified with imidazole show higher adsorption capacity for Rhodamine B. The other two chapters deal with the synthesis and characterization of novel composites of Cu-BTC and nanoporous carbons as well as with improvement of CO2 adsorption properties of Cu-BTC. The aforementioned composites exhibit a synergistic effect of the structure parameters derived from the both parent materials. As compared to the parent materials, the composites of Cu-BTC and porous carbons, show higher specific surface area and microporosity due to the newly created micropores at the interface, which enhance their CO2 adsorption capacity at ambient conditions. This work shows that a further improvement of the CO2 adsorption properties of Cu-BTC is possible by adjusting the molar ratio of Cu to BTC during synthesis. Namely, the ratio of 1.09:1.0 Cu to BTC produces MOF with improved textural properties and a remarkably high CO2 adsorption of 9.33 mmol/g at 0 oC and 1 bar.

Book Description
This book shows the promising future and essential issues on the storage of the supercritical gases, including hydrogen, methane and carbon dioxide, by adsorption with controlling the gas-solid interaction by use of designed nanoporous materials. It explains the reason why the storage of these gases with adsorption is difficult from the fundamentals in terms of gas-solid interaction. Also, the example of industrial application of natural gas storage with adsorption is described. It consists of 16 chapters which describe fundamentals, application, key nanoporous materials (nanoporous carbon, metal organic frame works, zeolites) and their storage performance for hydrogen, methane, and carbon dioxide. Thus, this book appeals to a wide readership of the academic and industrial researchers and it can also be used in the classroom for graduate students focusing on clean energy technology, green chemistry, energy conversion and storage, chemical engineering, nanomaterials science and technology, surface and interface science, adsorption science and technology, carbon science and technology, metal organic framework science, zeolite science, nanoporous materials science, nanotechnology, environmental protection, and gas sensors.
