Book Synopsis Nanostructured Catalysts by : Susannah L. Scott
Download or read book Nanostructured Catalysts written by Susannah L. Scott and published by Springer Science & Business Media. This book was released on 2008-04-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide insightful reviews of their areas of expertise, thus offering an overall picture of the state-- the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. Nanostructured materials with modified surfaces include those whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless and vapor deposition, or simple adsorption. These materials find important applications in catalysis, separation and environmental remediation. Materials with patterned surfaces, which are essential for the optoelectronics industry, constitute another important class of surface-modified nanostructured materials. Other materials are considered nanostructured because of their composition and internal organization.

Book excerpt: The proceedings of the VIIth International Symposium on the Scientific Bases for the Preparation of Heterogeneous Catalysts, are in line with the general scope of this series of events. Emphasis in all Symposia has been on the scientific aspects of the preparation of new and industrial catalysts, or on new methods of preparation, rather than on the catalytic reactions in which such solids are ultimately used. In the present context, the catalytic event itself has only been considered as another, though often decisive, method of catalyst characterization.
Book Synopsis Macromolecular Chemistry by : A D Jenkins
Download or read book Macromolecular Chemistry written by A D Jenkins and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Book Synopsis Ordered mesoporous silica COK-12: mesoscale tailoring, upscaling, continuous synthesis and application in the oxidative coupling of methane by : Colmenares, Maria
Download or read book Ordered mesoporous silica COK-12: mesoscale tailoring, upscaling, continuous synthesis and application in the oxidative coupling of methane written by Colmenares, Maria and published by Universitätsverlag der TU Berlin. This book was released on 2018-07-19 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ordered mesoporous silica (OMS) materials are a family of silica nanomaterials with pores ranging in size from 2 to 50 nm which are arranged periodically within the silica matrix. They have expanding applications in various fields of research, such as drug delivery, adsorption, separation and catalysis. COK-12 is an OMS produced by the soft-templating method, using the block copolymer P123 as a structure-directing agent. The synthesis takes place at room temperature under mild reaction conditions. In comparison with the most widely known OMS, the synthesis of COK-12 is more time efficient, inexpensive and environmentally friendly, yielding a material analogous to the well-known SBA-15. This thesis encompasses investigations regarding the production of the ordered mesoporous silica material (OMS) known as COK-12, in terms of upscaling of the synthesis and tailoring of the size and shape of its characteristic hexagonal pore structure. Batch upscaling of the synthesis yielded a material with nearly identical properties to that of the original COK-12. Upscaling of the COK-12 synthesis was also studied in continuous mode. The installation and operation of a continuous COK-12 production unit was carried out with the aim to determine the possibility of large-scale production of COK-12 with consistent material properties. COK-12 was produced in continuous mode by varying the time of aging of the COK-12 slurry and the flow rate of the feed streams, yielding materials with properties nearly identical to those of the original COK-12. COK-12 was used as a support for the Na2WO4-Mn/SiO2 catalyst for the oxidative coupling of methane reaction in various forms (powder, granular produced by pressing and monolithic), showing promising results comparable to the enhanced activity of the catalyst supported on the SBA-15. The advantage of using COK-12 over other OMS materials is that the facile nature of COK-12 synthesis makes it a viable candidate for industrial production of the Na2WO4-Mn/SiO2 catalyst, if paired with appropriate pelletizing and preparation method. The introduction of hexane and polypropylene glycol (PPG) as micellar swelling agents into the original COK-12 synthesis was studied in order to tailor the mesoporous structure of the system. Hexane was used as a micelle expander and as an agent to produce silica mesocellular foams, with “ink-bottle” shaped pores with a larger diameter than that of the original COK-12. By adding PPG into the synthesis, the shift of the mesostructure of COK-12 from 2D hexagonal to a multilamellar vesicular configuration was studied, resulting in the progressive formation of this type of material with increasing concentration of PPG. The flexibility of the COK-12 synthesis in terms of upscaling and tailoring of the mesostructure was examined throughout this work, with an aim to contribute to the existing and expanding knowledge regarding more versatile, sustainable and possibly industrial OMS production. Ordered Mesoporous Silica (OMS) gehört zu der Familie der Silica-Nanomaterialien mit periodisch angeordneten Mesoporen im Größenbereich zwischen 2 und 50 nm. Diese werden zunehmend in unterschiedlichen Forschungsfeldern wie Medikamentenfreisetzung, Adsorption, Separation und Katalyse eingesetzt. COK-12 ist ein OMS, das über eine Soft-Templating-Methode unter Nutzung des Blockcopolymers P123 als strukturbestimmenden Zusatz erzeugt wird. Die Synthese erfolgt bei Raumtemperatur unter milden Reaktionsbedingungen. Im Vergleich zu den am weitesten bekannten OMS-Materialien ist die Synthese von COK-12 zeiteffizient, günstig und umweltfreundlich. Dabei wird ein OMS-Material analog zu dem bereits etablierten SBA-15 erzeugt. Die vorliegende Dissertation umfasst die Synthese eines als COK-12 bekannten OMS-Materials, dem Scale-Up der Synthese sowie die Anpassung und Modifizierung der ursprünglich hexagonal-angeordneten Mesoporen bezüglich Porengrößen und Porenform. Das diskontinuierliche Scale-Up im Batchprozess führt zu nahezu identischen Materialeigenschaften im Vergleich zu dem ursprünglichen COK-12. Ein Scale-Up der COK-12-Synthese wurde zusätzlich im kontinuierlichen Prozess erprobt. Dessen Installation und Operation wurde mit dem Ziel durchgeführt, um die Möglichkeit einer Produktion von großen Mengen an COK-12 mit einheitlichen Materialeigenschaften zu validieren. Durch eine Variation der Alterungszeit als auch der Fließrate der Lösungen konnte COK-12 im kontinuierlichen Prozess mit nahezu identischen Eigenschaften wie das ursprüngliche COK-12 erzeugt werden. COK-12 wurde erfolgreich in verschiedenen Formen (Pulver, Pressgranulate und Monolithe) als Trägermaterial für Na2WO4-Mn/SiO2-Katalysatoren für die Oxidative Kopplung von Methan eingesetzt. Die resultierenden Aktivitäten ist sind vergleichbar mit denen des auf SBA-15-geträgerten Katalysators Der Vorteil der Nutzung von COK-12 im Vergleich zu anderen OMS-Materialien liegt in der vergleichsweise simplen COK-12-Synthese, weshalb es ein interessanter Kandidat für eine mögliche industrielle Produktion des Na2WO4-Mn/SiO2-Katalysators ist, wenn wenn geeignete Pelletierungs- und Herstellungsmethoden angewendet werden. Die Zugabe von Hexan und Polypropylenglykol (PPG) zur Aufweitung der Mizellen in der ursprünglichen COK-12-Synthese wurde untersucht, um die mesoporöse Struktur des Systems zu variieren. Hexan wurde eingesetzt zur Aufweitung der Mizellen und als Hilfsmittel zur Produktion mesozellulärer Silica-Schäume mit „ink-bottle“-förmigen Poren sowie vergrößertem Porendurchmesser im Vergleich zu denen des ursprünglichen COK-12. Durch die Zugabe von PPG in die Synthese verändert sich die Mesoporenstruktur der ursprünglichen hexagonalen 2D-Struktur zu einer multilamellaren vesikulären Anordnung, die mit zunehmender PPG-Konzentration verstärkt wird. Die Flexibilität der COK-12-Synthese wurde in dieser Arbeit in Bezug auf ein Scale-Up und eine Porenmodifikation weitreichend untersucht, mit dem Ziel das existierende Wissen in Bezug auf eine vielseitige, nachhaltige sowie eine potentielle Industrieproduktion der COK-12-Synthese zu entwickeln.
