Download or read book Synthesis and Characterization of Ordered Cage like Siliceous Mesostructures with Organic Pendant and Bridging Groups written by Rafal M. Grudzien and published by . This book was released on 2008 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ordered cage-like mesoporous materials were synthesized and characterized in terms of their surface, structural and adsorption properties. This dissertation covers three major topics devoted to the synthesis of cage-like silicas and organosilicas. The first topic involves the improvement of synthesis conditions of cage-like silicas such as SBA-16 and FDU-1. Special emphasis was given to the study of influence of different synthesis parameters, such as variations of the TEOS/template ratio, inorganic salt, the self-assembly time, and template removal procedure. It was shown that in order to obtain FDU-1 with uniform pore entrances, large cage diameter and high pore volume, optimal triblock copolymer/silica and salt/template ratios should be within 135:1 and 2.5:1, respectively. In addition, the first synthesis step can be shortened to six hours of the original 24 without diminishing the quality of the resulting FDU-1 materials. A two-step template removal method that combines partial extraction and temperature-controlled calcination was demonstrated to be an effective way for complete removal of the template. The second topic includes the fabrication and characterization of cage-like organosilicas with pendant groups, namely, vinyl, mercaptopropyl, ureidopropyl and imidazole. These organosilicas were prepared by co-condensation of desired organosilane and tetraethyl orthosilicate (TEOS) using the optimal synthesis procedures established for pure silicas. The co-condensation synthesis afforded materials with high loadings of organic groups up to 40%, large pore diameters, and narrow pore size distributions (PSDs). Moreover, the structural transformation from cubic to hexagonal was observed under low acidic conditions, double amount of polymer, and the addition of sodium chloride. The third topic involves the incorporation of bulky isocyanurate bridging groups into periodic mesoporous organosilicas (PMOs) using tris[3-(trimethoxysilyl)propyl]isocyanurate and TEOS. The resulting PMOs possess up to 30% of bridging groups, large pore volume and high surface area. The extraction, however, was insufficient to completely remove the template. An additional heating of extracted PMOs, therefore, was carried out to remove the remaining polymer. The aforementioned materials were characterized by nitrogen and argon adsorption, powder X-ray diffraction, transmission electron microscopy, elemental analysis, high resolution thermogravimetry, and Fourier-transform infrared spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: From the Introduction: Nanotechnology and its underpinning sciences are progressing with unprecedented rapidity. With technical advances in a variety of nanoscale fabrication and manipulation technologies, the whole topical area is maturing into a vibrant field that is generating new scientific research and a burgeoning range of commercial applications, with an annual market already at the trillion dollar threshold. The means of fabricating and controlling matter on the nanoscale afford striking and unprecedented opportunities to exploit a variety of exotic phenomena such as quantum, nanophotonic and nanoelectromechanical effects. Moreover, researchers are elucidating new perspectives on the electronic and optical properties of matter because of the way that nanoscale materials bridge the disparate theories describing molecules and bulk matter. Surface phenomena also gain a greatly increased significance; even the well-known link between chemical reactivity and surface-to-volume ratio becomes a major determinant of physical properties, when it operates over nanoscale dimensions. Against this background, this comprehensive work is designed to address the need for a dynamic, authoritative and readily accessible source of information, capturing the full breadth of the subject. Its six volumes, covering a broad spectrum of disciplines including material sciences, chemistry, physics and life sciences, have been written and edited by an outstanding team of international experts. Addressing an extensive, cross-disciplinary audience, each chapter aims to cover key developments in a scholarly, readable and critical style, providing an indispensible first point of entry to the literature for scientists and technologists from interdisciplinary fields. The work focuses on the major classes of nanomaterials in terms of their synthesis, structure and applications, reviewing nanomaterials and their respective technologies in well-structured and comprehensive articles with extensive cross-references. It has been a constant surprise and delight to have found, amongst the rapidly escalating number who work in nanoscience and technology, so many highly esteemed authors willing to contribute. Sharing our anticipation of a major addition to the literature, they have also captured the excitement of the field itself in each carefully crafted chapter. Along with our painstaking and meticulous volume editors, full credit for the success of this enterprise must go to these individuals, together with our thanks for (largely) adhering to the given deadlines. Lastly, we record our sincere thanks and appreciation for the skills and professionalism of the numerous Elsevier staff who have been involved in this project, notably Fiona Geraghty, Megan Palmer and Greg Harris, and especially Donna De Weerd-Wilson who has steered it through from its inception. We have greatly enjoyed working with them all, as we have with each other.

Download or read book Synthesis Adsorption and Structural Properties of Carbons with Uniform and Ordered Mesopores written by Kamil Gierszal and published by . This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various novel carbon mesostructures were explored with respect to their synthesis methods, adsorption properties as well as structural properties. Several important problems were studied including the structural ordering of ordered mesoporous carbons (OMCs), selection of carbon precursors, controlling the pore size, specific surface area and total pore volume of the resulting carbons. Ordered mesoporous silicas (OMSs) and silica colloidal templates were employed as hard templates. The obtained results have been divided into two major chapters dealing with: OMCs synthesized by using OMSs as templates and the mesoporous carbons templated by silica colloidal materials. The first aforementioned chapter presents the following problems. Two different OMSs, SBA-15 and KIT-6, were employed as hard templates and various carbon precursors including mesophase pitches of different softening points were used for the purpose to investigate the relation between the structure of OMCs and their adsorption properties. One of the most important conclusions was that the softening temperature of mesophase pitch clearly affected the structural properties of the resulting OMCs through the formation of different amount of micropores. The other studies involved the synthesis and characterization of OMCs templated by the SBA-16 silica with precisely controlled pore sizes. For this purpose, various carbon precursors were used - sucrose, acenaphthene and furfuryl alcohol. Two types of OMCs were prepared - the fully-filled inverse carbon replicas and the film-type inverse replicas of the SBA-16 silica. The second chapter deals with mesoporous carbons templated by silica colloidal crystals (SCCs) and disordered colloidal silicas. These templates served for the synthesis of mesoporous carbons from mesophase pitch as carbon precursors. The SCC was formed by evaporation method using the aqueous suspension of 46 nm uniform silica colloids, whereas the same method applied to 16 and 31 nm silica nanoparticles afforded only disordered aggregates. Application of these templates showed for the first time that it is possible to achieve the faithful inverse carbon replica of the well-ordered SCC composed of such small colloids. The other problem was devoted to graphitization of SCC-templated OMC. Here, well-graphitizable mesophase pitch as carbon source and SCC formed from 70 nm nanoparticles were employed. Carbonization at 1000 °C and subsequent graphitization of OMC at temperature as high as 2500 °C allowed one to obtain an excellent quality porous carbon ordered at nanoscale and at molecular level. The most important achievement reported in this dissertation was the synthesis of mesoporous carbons with extremely large pore volume and narrow pore size distribution. The structure was synthesized with the use of colloidal silica and resorcinol-crotonaldehyde as template and carbon precursor, respectively. The large pore volume could be obtained by formation of uniform thin carbon film on the pore walls of the aggregates of silica nanoparticles. Such prepared carbons with uniform mesopores reached the highest ever reported value of the total pore volume of 9̃ cm3/g. Also, new mathematical relations between basic adsorption parameters were derived. Various measuring techniques were used in order to characterize the adsorption and structural properties of the studied nanoporous materials. Among them were nitrogen adsorption, elemental analysis, powder X-ray diffraction (XRD), small angle X-ray scattering (SAXS), transmission and scanning electron microscopy (TEM/SEM), thermogravimetric analysis (TGA), Raman spectroscopy.
