Book excerpt: The dissertation begins with Chapter 1, which is a general introduction of the fundamental synthesis of mesoporous silica materials, the selective functionlization of mesoporous silica materials, and the synthesis of nanostructured porous materials via nanocasting. In Chapter 2, the thermo-responsive polymer coated mesoporous silica nanoparticles (MSN) was synthesized via surface-initated polymerization and exhibited unique partition activities in a biphasic solution with the thermally induced change. In Chapter 3, the monodispersed spherical MSN with different mesoporous structure (MCM-48) was developed and employed as a template for the synthesis of mesoporous carbon nanoparticles (MCN) via nanocasting. MCN was demonstrated for the delivery of membrane impermeable chemical agents inside the cells. The cellular uptake efficiency and biocompabtibility of MCN with human cervical cancer cells were also investigated. In addition to the biocompabtibility of MCN, MCN was demonstrated to support Rh-Mn nanoparticles for catalytic reaction in Chapter 4. Owing to the unique mesoporosity, Rh-Mn nanoparticles can be well distributed inside the mesoporous structure and exhibited interesting catalytic performance on CO hydrogenation. In Chapter 5, the synthesis route of the aforementioned MCM-48 MSN was discussed and investigated in details and other metal oxide nanoparticles were also developed via nanocasting by using MCM-48 MSN as a template. At last, there is a general conclusion summarized in Chapter 6.

Download or read book Synthesis of Ordered Mesoporous Materials Via Microwave Processing and Highly Heteroatom Doped Ordered Mesoporous Carbons for Energy Storage written by Yanfeng Xia and published by . This book was released on 2018 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ordered mesoporous materials, with pore diameter between 2 nm to 50 nm, have drawn researchers interests due to their superb properties including large surface area, uniform and adjustable pore architecture and good mechanical property, which allow a variety of different applications of the mesoporous materials, including catalysis, separation, purification, sensing and energy storage. Researchers have also reported different functionalization strategies of these mesoporous materials to improve the properties, such as improving electrochemical property by heteroatom doping of mesoporous carbon. One generalized synthetic strategy to synthesize ordered mesoporous materials is soft templating method. The functionalization of these mesoporous materials, such as heteroatom doping, can sometimes to lead ordered porous structure collapse, which is usually due to structure deformation during high temperature treatment. For instance, it is challenging to synthesize ordered mesoporous metal oxide with high crystalline pore wall with soft-templating method, as the growth of the crystals can deform the ordered porous structure. Meanwhile, it is difficult to synthesize ordered mesoporous carbon with high doping level (>10 at%) via soft-templating strategy as well, since the rapid doping reaction at high temperature can lead to ordered structure collapse due to the high vapor pressure generated by doping reactions. Here, we demonstrate several facile synthetic routes to fabricate highly crystalline ordered mesoporous metal oxide and heteroatom doped ordered mesoporous carbon. The application of the nitrogen doped mesoporous carbons in energy storage has also been discussed in this dissertation.Ordered mesoporous manganese oxide has been reported to be useful in energy storage due to its good electrochemical property, as the transition metal manganese has half-filled 3d orbital, which allows it to donate or accept electrons. However, synthesizing ordered mesoporous manganese oxide with high crystallinity with soft-templating strategy is challenging, as the crystal formation during thermal treatment can deform the ordered porous structure. In this dissertation, the synthesis of ordered mesoporous crystalline manganese oxide films is achieved by microwave-assisted processing to convert manganese carbonate precursor to the oxide, remove the polymeric template and crystallize the Mn3O4, all within 1 min. The microwave heating in this case is primarily induced by the microwave cross-section of the substrate (silicon wafer), together with the absorption of microwaves by manganese oxide to provide local energy, which can provide energy for nucleation/crystallization. Conversely, heating manganese carbonate in a muffle furnace at an analogous surface temperature leads to nanostructure collapse with low crystallinity. Apart from the synthesis of highly crystalline ordered mesoporous metal oxide, we also demonstrate the functionalization of ordered mesoporous carbon via heteroatom doping. Doped carbons can exhibit enhanced electronic, electrochemical and mechanical properties compared with un-doped carbons. These properties enable their use in applications, such as photovoltaics, catalysis and energy storage. For these applications, nano porosity and high heteroatom doping are generally desirable due to large surface area provided by nanoporous structure and improved properties contributed by heteroatom doping. However, it is challenging to achieve high content of heteroatoms doped carbons as well as maintaining the nanoporous structure. One common method of doping is to use heteroatom containing polymer precursors and carbonizing to synthesize doped carbon, where heteroatom content is limited by the number density of heteroatoms in the precursors. Additionally, during calcination, the nanoporous structure can collapse due to the contraction of pores. In this dissertation, a generalized synthetic strategy for highly doped ordered mesoporous carbons is reported. High concentrations of heteroatom doping in ordered mesoporous carbon is achieved by infiltration of molten dopants into silica reinforced mesoporous crosslinked polymer (phenolic resol) bi-continuous framework and subsequent carbonization. This method is demonstrated to generate ordered mesoporous carbons with high heteroatom content (> 10%) for a wide variety of elements including nitrogen, boron, sulfur and phosphorus, with ordered structure preserved. With the generalized synthetic route, nitrogen doped multi-shell hollow carbon are fabricated as a matrix material for Lithium-sulfur batteries. The hierarchical hollow structure and chemical decoration (heteroatom doping) of carbon framework can help to suppress polysulfide shuttling, while the macropore provides large pore volume to increase sulfur loading. The nitrogen doped sample shows better cycle stability compared with un-doped sample. Given that this hollow structure with a macropore can increase sulfur loading, the specific capacity is much lower compared with other cases where the pores are much smaller because of the low conductivity of sulfur.In addition, we also systematically investigate how nitrogen doping influences the rate that molten sulfur can infiltrate and the overall extent of pore filling of highly ordered mesoporous doped carbons via in-situ small angle x-ray scattering (SAXS). Nitrogen doping introduces polar bonds to the carbon framework, which can slow down the diffusion of nonpolar sulfur molecules into porous carbon. These in-situ SAXS measurements provide insights about kinetics information for diffusion of sulfur into mesopores and how the surface chemistry of nitrogen doped carbon can significantly hinder the infiltration of the mesopores by sulfur. In summary, this dissertation focuses on the functionalization of ordered mesoporous material without losing the ordered structure, as well as the application of nitrogen doped carbon in energy storage.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the fundamental properties, preparation routes and applications of a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). Mesoporous silicas are amorphous inorganic materials which have silicon and oxygen atoms in their framework with pore size ranging from 2 to 50 nm. They can be synthesized from surfactants as templates for the polycondensation of various silicon sources such as tetraalkoxysilane. In general, mesoporous silica materials possess high surface areas, tunable pore diameters, high pore volumes and well uniformly organized porosity. The stable chemical property and the variable ability for chemical modification makes them ideal for many applications such as drug carrier, sensor, separation, catalyst, and adsorbent. Among such mesoporous silicas, in 1999, three groups in Canada, Germany, and Japan independently developed a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). The organic functional groups in the frameworks of these solids allow tuning of their surface properties and modification of the bulk properties of the material. The book discusses the properties of PMOs, their preparation, different functionalities and morphology, before going on to applications in fields such as catalysis, drug delivery, sensing, optics, electronic devices, environmental applications (gas sensing and gas adsorption), biomolecule adsorption and chromatography. The book provides fundamental understanding of PMOs and their advanced applications for general materials chemists and is an excellent guide to these promising novel materials for graduate students majoring in chemical engineering, chemistry, polymer science and materials science and engineering.
