This book was released on 2011 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vanadium oxide particles supported on titania are known to catalyze a number of reactions, including the selective oxidation of methanol to formaldehyde. Although the catalytic activity of this system has been widely studied, several questions related to the exact compositions and structures of the active species remain unanswered. In an effort to gain a deeper fundamental understanding of these catalysts, we utilize a unique apparatus which allows us to deposit mass-selected Vx and VxOy clusters on single-crystal rutile TiO2(110)-(1x1) in ultra high vacuum.

Available in PDF, EPUB and Kindle. Book excerpt: With the recent advent of commercial ceramic membranes, inorganic membranes are receiving much attention as unique separators and reactors due to their excellent thermal and chemical stabilities. This volume provides an extensive and integrated survey of the science and technology of inorganic membranes.Various methods for making dense metal and solid electrolyte membranes and porous inorganic membranes with tortuous and nearly straight pores are provided. These inorganic membranes, ranging from ceramics to metals to inorganic polymers, can be characterized by many techniques indicative of their separation performance under idealized as well as application conditions. In addition to many commercial liquid-phase applications, inorganic membranes have been used industrially for gas diffusion and particle filtration and demonstrated for the important high-temperature gas separation and membrane reactor applications. Approximately half of the book is devoted to the subject of inorganic membrane reactors. Useful data in many tables and figures and extensive literature and patent information are given throughout the book for further study.The book is a valuable reference for researchers as well as process engineers who are involved in membrane and separation technology. Chemical engineers, chemists and material scientists should also find the text a comprehensible introduction to the subject.
Download or read book Aerogels Handbook written by Michel Andre Aegerter and published by Springer Science & Business Media. This book was released on 2011-06-10 with total page 929 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerogels are the lightest solids known. Up to 1000 times lighter than glass and with a density as low as only four times that of air, they show very high thermal, electrical and acoustic insulation values and hold many entries in Guinness World Records. Originally based on silica, R&D efforts have extended this class of materials to non-silicate inorganic oxides, natural and synthetic organic polymers, carbon, metal and ceramic materials, etc. Composite systems involving polymer-crosslinked aerogels and interpenetrating hybrid networks have been developed and exhibit remarkable mechanical strength and flexibility. Even more exotic aerogels based on clays, chalcogenides, phosphides, quantum dots, and biopolymers such as chitosan are opening new applications for the construction, transportation, energy, defense and healthcare industries. Applications in electronics, chemistry, mechanics, engineering, energy production and storage, sensors, medicine, nanotechnology, military and aerospace, oil and gas recovery, thermal insulation and household uses are being developed with an estimated annual market growth rate of around 70% until 2015. The Aerogels Handbook summarizes state-of-the-art developments and processing of inorganic, organic, and composite aerogels, including the most important methods of synthesis, characterization as well as their typical applications and their possible market impact. Readers will find an exhaustive overview of all aerogel materials known today, their fabrication, upscaling aspects, physical and chemical properties, and most recent advances towards applications and commercial products, some of which are commercially available today. Key Features: •Edited and written by recognized worldwide leaders in the field •Appeals to a broad audience of materials scientists, chemists, and engineers in academic research and industrial R&D •Covers inorganic, organic, and composite aerogels •Describes military, aerospace, building industry, household, environmental, energy, and biomedical applications among others

Download or read book X ray Absorption Fine Structure For Catalysts And Surfaces written by Yasuhiro Iwasawa and published by World Scientific. This book was released on 1996-05-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray absorption fine structure (XAFS) is a powerful technique in characterization of structures and electronic states of materials in many research fields including, e.g., catalysts, semiconductors, optical ingredients, magnetic materials, and surfaces. This characterization technique could be applied in a static or a dynamic state (in-situ condition). The XAFS can provide information that is not accessible by other techniques for characterization of materials, particularly catalysts and related surfaces. Furthermore, XAFS can provide a molecular-level approach to the study of reaction mechanisms for the understanding of catalysts and development of new catalysts. A number of synchrotron radiation facilities have been planned to be built in Asian countries in addition to the high-brilliant synchrotron radiation facilities under construction in the USA, Europe, and Japan. The applications of XAFS have now expanded to catalytic chemistry and engineering, surface science, organometallic chemistry, materials science, solid-state chemistry, geophysics, etc. This book caters to a wide range of researchers and students working in the domain or related topics.

Download or read book Synthesis Methodology Affecting Vanadium Titanium Silicalite 1 Catalyst written by and published by . This book was released on 2006 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vanadium titanium silicalite-1 (V/TS-1) samples (Si/Ti = 50, Si/V = 100) are synthesized by using hydrothermal method. To determine a suitable synthesis method that can control the amounts of titanium and vanadium in the MFI structure of synthesized catalysts, the effects of synthesis methodology (the vanadium salt addition method) and type of vanadium salt (VCl[subscript 3], VO(acac)[subscript 2] and V[subscript2]O[subscript 5] ) are investigated. The synthesized catalysts are characterized using various techniques such as XRF, XRD, BET, SEM, FT-IR, NH -TPD and ESR. The catalytic behavior is evaluated using the gas phase oxidation of 2-propanol (8 vol% oxygen, 5 vol% 2-propanol, balanced with argon). The catalytic reaction is carried out in a microreactor at a temperature range 100-500 degree Celsius, atmosphere pressure. This research shows that the vanadium salt addition method and the type of vanadium salt do not significantly affect the MFI structure as well as the reaction pathway. During the synthesis procedure, the vanadium species existing in the part of cation complex when it dissolved in aqueous solution is easier to be incorporated into the TS-1 structure than the ones exist in the part of anion complex. The surface area of the synthesized catalysts decrease inversely with the amount of vanadium incorporated. The NH[subscript 3] -TPD results indicate that the synthesized catalysts have two different types of acid site; the weaker one desorbed NH[subscript 3] at the temperature range 135-145 degree Celsius and the stronger one desorbed NH [subscript 3] at around 222-242 degree Celsius. For catalytic behavior, it is found that the synthesized V/TS-1 catalysts which have the vanadium active species derived from VCl [subscript 3] bonded on its surface are active in the 2-propanol oxidation and it can inhibit the dehydration and the combustion of 2-propanol. However, the ones which have the vanadium active species derived from VO(acac)[subscript 2] bonded on the catalyst surface do not be active in the 2-propanol oxidation but it can inhibit the 2-propanol combustion. Moreover, it is found that V[subscript 2]O[subscript 5] is not the suitable vanadium source for this synthesis method because V[superscript 5+] tends to stay in the anion complex which is more difficult to be incorporated into the TS-1 structure.
