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. It consists of 14 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.

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

Nanoporous materials, such as metal-organic frameworks (MOFs), have enormous internal surface areas. Their consequent adsorption properties demonstrate promise towards solving energy-related problems in gas storage and gas separations. Owing to their modular and versatile chemistry, millions of possible nanoporous materials can be synthesized. This vast chemical space allows a material to be tailor-made or fine-tuned to target specific adsorbate molecules and conditions. In this thesis, we utilize molecular models and simulations of gas adsorption in both existing and predicted nanoporous material structures to accelerate the discovery of new materials targeted for gas storage and separations at specific conditions. In the first part of this work, we approach the problem of identifying an optimal porous material to densify natural gas for storage onboard vehicles as fuel. We developed a series of statistical mechanical models to find the thermodynamic parameters that optimize the deliverable capacity of a material. We conclude that the heat of adsorption, which is a commonly used metric to evaluate materials for natural gas storage, is a misleading metric because the optimal heat of adsorption depends on the pore size. Our models also reveal that adsorbate-adsorbate attractions-- in the case where multiple methane molecules can fit into a pore-- can enhance the deliverable capacity. Next, we carried out a high-throughput computational screening of metal-organic frameworks, porous polymer networks, zeolites, and zeolitic imidazolate frameworks for natural gas storage. The data that we collected provide candidate structures for synthesis, reveal relationships between structural characteristics and performance, and suggest that it may be difficult to reach the current Advanced Research Project Agency-Energy (ARPA-E) deliverable capacity target. To assess thermodynamic limits to the methane deliverable capacity, we then built a model of an extreme scenario where an energy field can be created without taking up space with material. This model suggests that, while the failure to reach the ARPA-E storage target is due to material design constraints rather than purely thermodynamic constraints, the ARPA-E storage target is ambitiously close to the thermodynamic limit. In the second part of this work, we approach the problem of identifying a material that selectively adsorbs xenon over krypton. With over half a million nanoporous material structures to consider as candidate adsorbents, the computational cost of a brute-force computational screening strategy was prohibitive. Instead, we employed a machine learning algorithm, a random forest, to learn the relationship between quickly computed structural descriptors and Xe/Kr selectivity, which is more expensive to compute. The trained random forest allowed us to rule out a large percentage of the materials on the basis of quickly-computed structural descriptors. Our machine learning accelerated screening pinpoints top candidates on which to focus experimental efforts and elucidates structure-property relationships for design guidelines for a Xe-selective material. As we are now working with mixed gas adsorption, we developed a user-friendly software package in Python, pyIAST, for ideal adsorbed solution theory (IAST) calculations. IAST is a thermodynamic framework to predict mixed gas adsorption from pure-component adsorption isotherms, which are easier to measure. We provide practical guidelines for applying IAST. Finally, we carry out a high-throughput computational screening of metal-organic frameworks for capturing Xe from air at dilute conditions, a separation encountered in used nuclear fuel reprocessing. Our computational screening, facilitated by a parallelized code on GPUs, predicted a metal-organic framework, SBMOF-1, to be among the most Xe-selective. Our experimental collaborators synthesized and tested SBMOF-1 and found it to exhibit the highest Xe/Kr selectivity and Xe Henry coefficient reported in the literature. Column-breakthrough experiments reveal that SBMOF-1 is a near-term material for capturing xenon from the off-gases of used nuclear fuel reprocessing plants. This is a rare case of a computation-assisted materials discovery.

This text discusses the synthesis, characterization, and application of metal-organic frameworks (MOFs) for the purpose of adsorbing gases. It provides details on the fundamentals of thermodynamics, mass transfer, and diffusion that are commonly required when evaluating MOF materials for gas separation and storage applications and includes a discussion of molecular simulation tools needed to examine gas adsorption in MOFs. Additionally, the work presents techniques that can be used to characterize MOFs after gas adsorption has occurred and provides guidance on the water stability of these materials. Lastly, applications of MOFs are considered with a discussion of how to measure the gas storage capacity of MOFs, a discussion of how to screen MOFs to for filtration applications, and a discussion of the use of MOFs to perform industrial separations, such as olefin/paraffin separations. Throughout the work, fundamental information, such as a discussion on the calculation of MOF surface area and description of adsorption phenomena in packed-beds, is balanced with a discussion of the results from research literature.
