Available in PDF, EPUB and Kindle. Book excerpt: The report presents a general discussion of electronic surface states and their possible electronic and catalytic effects. It also presents a method by which the temperature-dependence of the catalyst's conductivity can be used to elicit information on the disposition of the surface states relative to the bulk band structure. The catalyst was ZnO in powder form and an impedance technique was used to measure its conductivity under single gas (CO and O2) and differential reaction (2CO + 02 yields 2CO2) ambients. Oxygen acceptor surface states appear to have a dominant influence over the catalyst's conductivity even at O2 pressures as low as 0.00001 torr and in reaction mixture containing greater than 4 parts CO to one part O2. The apparent donor effect of adsorbed CO appears to result from the interaction with adsorbed or lattice oxygen rather than from the formation of a donor-like CO adsorption state. The experimental measurements tend to confirm the energy band structure model of this semiconductor catalyst and reveal certain features of interest for the electronic theory of catalysis. However, it does appear that powder systems may be too complex to deal with quantitatively at the present stage of development of electronic surface state theories. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Through their application in energy-efficient and environmentally friendly devices, zinc oxide (ZnO) and related classes of wide gap semiconductors, including GaN and SiC, are revolutionizing numerous areas, from lighting, energy conversion, photovoltaics, and communications to biotechnology, imaging, and medicine. With an emphasis on engineering and materials science, Handbook of Zinc Oxide and Related Materials provides a comprehensive, up-to-date review of various technological aspects of ZnO. Volume Two focuses on devices and nanostructures created from ZnO and similar materials. The book covers various nanostructures, synthesis/creation strategies, device behavior, and state-of-the-art applications in electronics and optoelectronics. It also provides useful information on the device and nanoscale process and examines the fabrication of LEDs, LDs, photodetectors, and nanodevices. Covering key properties and important technologies of ZnO-based devices and nanoengineering, the handbook highlights the potential of this wide gap semiconductor. It also illustrates the remaining challenging issues in nanomaterial preparation and device fabrication for R&D in the twenty-first century.

Download or read book The Chemisorptive Bond written by Alfred Clark and published by Elsevier. This book was released on 2012-12-02 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemisorptive Bond: Basic Concepts describes the basic concepts of the chemisorptive bond on solid surfaces from the simple analogies with ordinary chemical bonds to the quantum-mechanical approaches. This book is composed of 10 chapters and begins with discussions of simple formulas for correlating measurable quantities in chemisorptions and catalysis. The succeeding chapters deal with theories based on quantum-mechanical principles that describe the mutual interactions of atoms of the solid and foreign atoms on the surface. The remaining chapters consider the possible arrangements of ligands about a central metal atom, including octahedral, tetrahedral, cubic, and square planar, and how these arrangements affect chemisorption. This book will be of great value to chemical engineers and researchers.
