This book was released on 1990 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the effects of surface structure, dispersion, and support on the adsorption, catalytic, and electronic properties of cobalt/alumina is described, the objectives of which were to determine (1) the effects of surface structure and metal dispersion on the adsorption and catalytic properties of cobalt and (2) the effects of direct electronic interactions between metal clusters and support, on the adsorption, catalytic and electronic properties of cobalt supported on alumina. Effects of surface structure and dispersion on the adsorption, activity/selectivity, and electronic properties of Co/W single crystal surfaces and alumina-supported cobalt were investigated in a surface investigation, lab reactor studies, TPD/TPSR studies, and a Moessbauer spectroscopy study. The structure, stability, surface electronic properties, and chemisorptive properties of vapor-deposited cobalt overlayers (0-4 ML) on W(110) and W(100) were studied by Auger electron spectroscopy, low energy electron diffraction, work function changes, and temperature programmed desorption (TPD) of cobalt, hydrogen, and carbon monoxide. The CO chemisorptive properties of the two cobalt overlayers are quite different, CO adsorption being dissociative on the W(100) surface and nondissociative on the W(110) surface; comparison of the results with those for Ni/W(100) indicate that Co/W(100) dissociates CO as a result of electronic interaction with the tungsten substrate.

Book excerpt: Catalysts are required for a variety of applications and researchers are increasingly challenged to find cost effective and environmentally benign catalysts to use. This volume looks at modern approaches to catalysis and reviews the extensive literature. Chapters highlight reactions active under oxidative coupling of methane conditions and how they are interlinked, heterogeneous nickel catalysts and their use in laboratory and industry, the reaction mechanism of heterogeneous catalysis with the surface science probe, the concepts of electroless deposition (ED) methods for preparation of true bimetallic catalysts, the general subject of metal-support interactions occurring over ruthenium-based catalysts and benzene as the target volatile organic compound (VOC). Appealing broadly to researchers in academia and industry, these illustrative chapters bridge the gap from academic studies in the laboratory to practical applications in industry not only for catalysis field but also for environmental protection. The book will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.

Available in PDF, EPUB and Kindle. Book excerpt: Many important industrial chemical processes rely heavily on catalysis and so researchers are always on the lookout for alternative catalytic materials that may improve existing processes or lead to new ones. Families of alternative catalytic materials currently being investigated include the carbides, nitrides and phosphides as well as amorphous boron catalysts. The addition of carbon, nitrogen or phosphorous to transition metals and the creation of boron-transition metal alloys leads to catalytic materials that have interesting properties, with applications in a range of different reactions, including electrocatalysis. This book provides a comprehensive account of the preparation, characterisation and application of these catalytic materials. It is an important reference for researchers and industrialists working in heterogeneous catalysis and materials chemistry.

Book excerpt: A significant part of the effort in catalysis research is based on an understanding that a more complete knowledge of the nature and behavior of reactive intermediates or chemisorbed complexes enables to produce better catalysts for industrial processes. The supporting cash flow is certainly based on this assumption. This volume presents written accounts of four different sectors of this effort.
