Advances In Nanoporous Materials

Advances in Nanoporous Materials is a collection of comprehensive reviews of lasting value to the field. The contributions cover all aspects of nanoporous materials, including their preparation and structure, post-synthetic modification, characterization and use in catalysis, adsorption/separation, and all other fields of potential application, e.g., membranes, host/guest chemistry, environmental protection, electrochemistry, sensors, and optical devices. "Nanoporous materials" comprise all kinds of porous solids that possess pores in the range from about 0.2 nm up to 50 nm, irrespective of their chemical composition, their origin (natural or synthetic), and their amorphous or crystalline nature. Typical examples are zeolites and zeolite-like materials (e.g., crystalline microporous aluminophosphates and their derivatives), mesoporous oxides such as silica, metal organic frameworks, pillared clays, porous carbons, and related materials.

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,

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. Contents:Nanoporous Materials — An Overview (G Q Lu & X S Zhao)Advances in Mesoporous Materials Templated by Nonionic Block Copolymers (C Yu et al.)Zeolite/Mesoporous Molecular Sieve Composite Materials (D T On & S Kaliaguine)Chromium-Containing Ordered Nanoporous Materials (P Selvam)Surfactant-Templated Mesostructured Materials: Synthesis and Compositional Control (M S Wong & W V Knowles)Organic Host-Guest Structures in the Solid State (A Nangia)Nonsurfactant Route to Nanoporous Phenyl-Modified Hybrid Silica Materials (Y Wei et al.)3D Macroporous Photonic Materials Templated by Self Assembled Colloidal Spheres (Z C Zhou & X S Zhao)Hydrophobic Microporous Silica Membranes for Gas Separation and Membrane Reactors (S Giessler et al.)Synthesis and Characterization of Carbon Nanotubes for Hydrogen Storage (H-M Cheng et al.)Physical Adsorption Characterization of Ordered and Amorphous Mesoporous Materials (M Thommes)Molecular Simulation of Adsorption in Porous Materials (D Nicholson)Surface Functionalization of Ordered Nanoporous Silicates (X S Zhao et al.)Surface Alumination of Mesoporous Silicates (R Mokaya)Acidity Measurement of Nanoporous Aluminosilicates — Zeolites and MCM-41 (J Zheng et al.)Nanocatalysts Prepared by the Molecularly Designed Dispersion Process (P Cool et al.)Acidity-enhanced Nanoporous Catalytic Materials (F-S Xiao & Y Han)Modified Mesoporous Materials as Acid and Base Catalysts (D J Macquarrie)Lewis Acid/Base Catalysts Supported on Nanoporous Silica as Environmental Catalysts (V R Choudhary & B S Uphade)Nanoporous Catalysts for Shape-Selective Synthesis of Specialty Chemicals: A Review of Synthesis of 4,4'-Dialkylbiphenyl (J-P Shen & C Song)Catalysis Involving Mesoporous Molecular Sieves (W S Ahn et al.)Adsorption and Transport in Nanoporous Materials (J P B Mota)Adsorption of Organic Molecules in Nanoporous Adsorbents from Aqueous Solution (R Denoyel)Functionalized Nanoporous Adsorbents for Environmental Remediation (M C Burleigh & S Dai)Nanoporous Adsorbents for Air Pollutant Removal (P Le Cloirrec)Bioadsorption and Separation with Nanoporous Materials (A Daehler et al.)Nanoporous Materials as Supports for Enzyme Immobilization (H H P Yiu & P A Wright)A Novel Non-surfactant Route to Nanoporous Materials and its Biological Applications (Y Wei & K-Y Qiu) Readership: Researchers in nanotechnology, chemical engineering, physical chemistry and solid state chemistry.

The developments in the area of ordered nanoporous solids have moved beyond the traditional catalytic and separation uses and given rise to a wide variety of new applications in different branches of chemistry, physics, material science, etc. The activity in this area is due to the outstanding properties of nanoporous materials that have attracted the attention of researchers from different communities. However, recent achievements in a specific field often remain out of the focus of collaborating communities.

Nanoporous Materials III contains the invited lectures and peer-reviewed oral and poster contributions to be presented at the 3rd Conference on Nanoporous Materials, which will be hosted in Ottawa, Canada, June 2002. The work covers complementary approaches to and recent advances in the field of nanostructured materials with pore sizes larger than 1nm, such as periodic mesoporous molecular sieves M41S and FSM16 and related materials including clays, carbon molecular sieves, colloidal crystal templated organic and inorganic materials, porous polymers and sol gels. The broad range of topics covered in relation to the synthesis and characterization of ordered mesoporous materials are of great importance for advanced adsorption, catalytic and separation processes as well as the development of nanotechnology. The contents of this title are based on topics to be discussed by invited lecturers, which deal with periodic mesoporous organosilicas, stability and catalytic activity of aluminosilicate mesostructures, electron microscopy studies of ordered materials, imprinted polymers and highly porous metal-organic frameworks. The other contributions deal with tailoring the surface and structural properties of nanoporous materials, giving a detailed characterization as well as demonstrating their usefulness for advanced adsorption and catalytic applications.

Atoms and molecules in all states of matter are subject to continuous irregular movement. This process, referred to as diffusion, is among the most general and basic phenomena in nature and determines the performance of many technological processes. This book provides an introduction to the fascinating world of diffusion in microporous solids. Jointly written by three well-known researchers in this field, it presents a coherent treatise, rather than a compilation of separate review articles, covering the theoretical fundamentals, molecular modeling, experimental observation and technical applications. Based on the book Diffusion in Zeolites and other Microporous Solids, originally published in 1992, it illustrates the remarkable speed with which this field has developed since that time. Specific topics include: new families of nanoporous materials, micro-imaging and single-particle tracking, direct monitoring of transient profiles by interference microscopy, single-file diffusion and new approaches to molecular modeling.

This book presents synthesis, characterization, and applications of macroporous, mesoporous, nanoporous, hierarchical porous, porous metals, and porous ceramics. Special emphasis is given to the preparation of porous activated carbon materials and porous ionic liquid-derived materials for CO2 emissions mitigation. Additionally, a chapter includes the physical and mathematical modeling in porous media. Many analytical techniques for characterization are discussed in this book. Also, the biomedical and industrial applications of porous materials in adsorption, catalysis, biosensors, drug delivery, nanotechnology are described. The content helps solving fundamental and applied problems in porous materials with length scales varying from macro- to nano-level.
