Functional Nanoporous Materials

With pore sizes up to 100 nm, the term "nanoporous" covers a wide range of material classes. A broad field of applications has arisen from the diversity of unique structures and properties of nanoporous materials. Recent research spans the range from fundamental studies of the behavior of atoms and molecules in confined space, creative synthetic pathways for novel materials, to applications in high-performance technologies. This Special Issue collects current studies about the progress in the development, characterization, and application of nanoporous materials, including (but not restricted to) mesoporous silica, carbon and metal oxides, porous coordination polymers, metal organic frameworks (MOFs), and covalent organic frameworks (COFs), as well as materials exhibiting hierarchical porosity. Their functionalities show promise for fields such as energy storage/conversion (e.g., photocatalysis and battery electrodes), sensing, catalysis, and their sorption properties for N2, CO2, NOx, or H2O, to name just a few.

In the past two decades, the field of nanoporous materials has undergone significant developments. As these materials possess high specific surface areas, well-defined pore sizes, and functional sites, they show a great diversity of applications such as molecular adsorption/storage and separation, sensing, catalysis, energy storage and conversion, drug delivery, and more. Nanoporous Materials: Synthesis and Applications surveys the key developments in the synthesis of nanoporous materials in a broad range from soft porous materials—such as porous organic and metal-organic frameworks—to hard porous materials, such as porous metals and metal oxides, and the significant advances in their applications to date. Topics Include: Synthetic approaches, characterization techniques, and applications of a variety of meso- and microporous polymers and organic frameworks Advances in the synthetic control of structures along with the function exploration of this new class of organic porous materials Synthesis and applications of nanoporous metal-organic frameworks, mesoporous silica, and nanoporous glass Synthesis of mesoporous carbons by a soft- and hard-templating method and their applications for supercapacitors and membrane separations Fabrication of nanoporous semiconductor materials Structural modification and functional improvement of layered zeolites Germanates and related materials with open-frameworks

Over the past decade, the research community has been paying particular attention to organic, inorganic and hybrid porous materials, mainly due to the plethora of promising applications offered by such architectures in areas as diverse as (nano)filtration and separation techniques, heterogeneous supported catalysis, template-assisted synthesis of nanomaterials, materials for phonic and thermic isolation as well as patterned nanomaterials for microelectronics and photovoltaics, as previously reported by numerous reviews in the field. This book provides current research on nanopores and nanoporous materials. Chapter One affords a critically selected survey of these elegant approaches toward functional nanoporous polymers and investigates their scope and limitations. Chapter Two focuses on the recent development on the nanoporous Montmorillonite clay and metal nanoparticles stabilization on the clay by different procedures and their catalytic applications for fine chemicals synthesis. Chapter Three presents an overview of the developments in soft nanoporous organic materials by self-assembly of peptide, polyamide and polyimide moieties. Chapter Four examines nano-drilling processing with transmission electron microscope (TEM).

As nanomaterials get smaller, their properties increasingly diverge from their bulk material counterparts. Written from a materials science perspective, Adsorption and Diffusion in Nanoporous Materials describes the methodology for using single-component gas adsorption and diffusion measurements to characterize nanoporous solids. Concise, yet comprehensive, the book covers both equilibrium adsorption and adsorption kinetics in dynamic systems in a single source. It presents the theoretical and mathematical tools for analyzing microporosity, kinetics, thermodynamics, and transport processes of the adsorbent surface. Then it examines how these measurements elucidate structural and morphological characteristics of the materials. Detailed descriptions of the phenomena include diagrams, essential equations, and fully derived, concrete examples based on the author's own research experiences and insight. The book contains chapters on statistical physics, dynamic adsorption in plug flow bed reactors, and the synthesis and modification of important nanoporous materials. The final chapter covers the principles and applications of adsorption for multicomponent systems in the liquid phase. Connecting recent advances in adsorption characterization with developments in the transport and diffusion of nanoporous materials, this book is ideal for scientists involved in the research, development, and applications of new nanoporous materials.

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
