Metal-Oxygen Clusters The Surface and Catalytic Properties of Heteropoly Oxometalates


Free Download John B. Moffat, "Metal-Oxygen Clusters: The Surface and Catalytic Properties of Heteropoly Oxometalates"
English | 2001 | pages: 317 | ISBN: 1475774796, 0306465078 | PDF | 3,0 mb
Metal-Oxygen Clusters is the first book, providing an overview of the surface chemistry and catalytic properties of heteropoly oxometalates. After a brief look at the early knowledge of heteropoly oxometalates, the book discusses the synthesis, characterization, structure, bulk properties and stability of these materials. The remainder and the largest portion of the book explores the properties of these solids as catalysts in acid-catalyzed and oxidation processes in supported or unsupported forms.

Green Approaches To Asymmetric Catalytic Synthesis

2011 | 140 Pages | ISBN: 940071453X | PDF | 6 MB
Nowadays, chirality is widely accepted as an important factor in molecular recognition processes and the biological activity of many pharmaceutical drugs and agrochemicals; this is confirmed by the continuous need for synthetic methods which lead to single or enriched enantiomers of such compounds. By presenting a review of the various and more recently developed approaches for both metal-transition and organocatalysis, this volume describes the development of "greener" asymmetric reactions which preserve stereoselectivity. The author summarizes the impressive amount of research that has been gathered within this field into three chapters focusing on: i)the search of alternative catalysts, ii) alternative solvents, and iii) alternative synthetic strategies and processes. For each topic, the fundamentals and some valuable applications are discussed.

Applications of X-ray Photoelectron Spectroscopy to Catalytic Studies


Free Download Applications of X-ray Photoelectron Spectroscopy to Catalytic Studies : From Routine Analysis to Cutting-Edge Surface Characterization (547 Pages)
by Spyridon Zafeiratos

X-ray photoelectron spectroscopy (XPS) has become a standard practice technique, and automated XPS facilities can be found in industry and in universities all over the world. This transformed XPS from an advanced characterization method for dedicated research, to a rather standard analysis technique of surface analysis. The catalyst’s surface state is probably the most prominent factor that influences the catalytic performance. It is therefore no surprise that XPS has become an indispensable tool in studies of solid catalysts. It has been directly used to investigate issues such as the surface composition of the active catalyst and reaction and deactivation mechanisms.
