Book excerpt: Nanostructured materials with tailored properties are regarded as a fundamental element in the development of future science and technology. Research is still ongoing into the nanosized construction elements required to create functional solids. The recently developed technique, nanocasting, has great advantage over others in terms of the synthesis of special nanostructured materials by the careful choice of suitable elements and nanoengineering steps. This new book summarizes the recent developments in nanocasting, including the principles of nanocasting, syntheses of novel nanostructured materials, characterization methods, detailed synthetic recipes and further possible development in this area. The book focuses on the synthesis of porous solids from the viewpoint of methodology and introduces the science of nanocasting from fundamental principles to their use in synthesis of various materials. It starts by outlining the principles of nanocasting, requirements to the templates and precursors and the tools needed to probe matter at the nanoscale level. It describes how to synthesize nano structured porous solids with defined characteristics and finally discusses the functionalization and application of porous solids. Special attention is given to new developments in this field and future perspectives. A useful appendix covering the detailed synthetic recipes of various templates including porous silica, porous carbon and colloidal spheres is included which will be invaluable to researchers wanting to follow and reproduce nanocast materials. Topics covered in the book include: * inorganic chemistry * organic chemistry * solution chemistry * sol-gel and interface science * acid-base equilibria * electrochemistry * biochemistry * confined synthesis The book gives readers not only an overview of nanocasting technology, but also sufficient information and knowledge for those wanting to prepare various nanostructured materials without needing to search the available literature.

Download or read book Synthesis and Characterization of CMK Porous Carbons Modified with Metals Applied to Hydrogen Uptake and Storage written by Marcos B. Gómez and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, we have shown that hopeful hydrogen storage material can be obtained by ordered mesoporous carbons (carbons mesostructured from Korea, CMK-1 and CMK-3) and modified with metal/cations species. The pristine CMK-1 and CMK-3 were synthesized by replication using MCM-48 and SBA-15 as hard templates and sucrose as a carbon source. Incorporation of metal species was carried out by wetness impregnation. The mesoporous materials modified were characterized by X-ray diffraction (XRD), X-ray photoelectron spectra (XPS), RAMAN, transmission electron microscopy (TEM), and adsorption/desorption N2 isotherms. Carbon modified with metal/cations shows a better capacity for hydrogen uptake than that of the mesoporous carbons. The evolution of high-pressure hydrogen adsorption measured at 77 K shows that composites can significantly enhance hydrogen adsorption capacity and hydrogen storage performance of carbon materials, proving to be prospective candidates for application in hydrogen storage. The improved activity and the larger performance of composite materials are attributed to improved dispersion of uniform metal/cations nanoparticles as well as to efficient use of the support, which may originate a high-surface area and pore volume, allowing a large dispersion of clusters.
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.
