Book Description
"XPS has become a mature 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 the reaction and deactivation mechanisms. Several excellent essays describe in detail the theoretical and practical aspects of X-ray photoelectron spectroscopy. The objective of the book is to provide a comprehensive overview of the current status and future perspectives of X-ray photoelectron spectroscopy dedicated to catalytic applications, including thermal catalysis, electrocatalysis, and photo(electro)catalysis. The book contains 13 chapters, starting with the necessary introduction of the technique background, including basic phenomena and instrumentation aspects. The second part of the book focuses on the presentation of long-established applications of the technique such as XPS studies of model catalysts. In the last part, the book describes relatively recent developments of this method for cutting edge surface characterization mainly using synchrotron X-ray radiation"--

Book Description
APPLICATION OF AMBIENT PRESSURE X-RAY PHOTOELECTRON SPECTROSCOPY Authoritative and detailed reference on ambient-pressure x-ray photoelectron spectroscopy for practitioners and researchers starting in the field Application of Ambient Pressure X-ray Photoelectron Spectroscopy to Catalysis introduces a relatively new analytical method and its applications to chemistry, energy, environmental, and materials sciences, particularly the field of heterogeneous catalysis, covering its background and historical development, its principles, the instrumentation required to use it, analysis of data collected with it, and the challenges it faces. The features of this method are described early in the text; the starting chapters provide a base for understanding how AP-XPS tracks crucial information in terms of the surface of a catalyst during catalysis. The second half of this book delves into the specific applications of AP-XPS to fundamental studies of different catalytic reactions. In later chapters, the focus is on how AP-XPS could provide key information toward understanding catalytic mechanisms. To aid in reader comprehension, the takeaways of each chapter are underlined. In Application of Ambient Pressure X-ray Photoelectron Spectroscopy to Catalysis, readers can expect to find detailed information on specific topics such as: Going from surface of model catalyst in UHV to surface of nanoparticle catalyst during catalysis Application of XPS from surface in UHV to surface in gas or liquid phase and fundamentals of X-ray spectroscopy Significance and challenges of studying surface of a catalyst in gaseous phase and instrumentation of ambient pressure X-ray photoelectron spectrometers Experimental methods of AP-XPS studies and difference in data analysis between AP-XPS and high vacuum XPS Ambient Pressure X-Ray Photoelectron Spectroscopy is an ideal resource for entry level researchers and students involved in x-ray photoelectron spectroscopy. Additionally, the text will appeal to scientists in more senior roles in academic and government laboratory institutions in the fields of chemistry, chemical engineering, energy science, and materials science.

Book Description
This volume outlines the physical and methodical concepts of X-ray photoelectron spectroscopy (XPS) specifically for surface studies using both inner and valence electron levels. It discusses the theory and practice of XPS qualitative and quantitative analysis of solid state surfaces and provides lists of extended experimental and theoretical data necessary for the determination of concentration and thin film thicknesses. In addition it covers the many problems concerning in-depth profiling, ion sputtering rate and damages of the structure of altered layers, as well as applications of angular dependence of the intensities and photoelectron diffraction for surface studies. Also provided are the applications of XPS for the investigations of catalysts, adsorption, electronic surface states, oxydation of semi-conductors and alloys, minerals, including lunar regolith and natural gold, glasses, radiation damage, surface diffusion, polymers, etc.

Book Description
X-ray photoelectron spectroscopy (XPS) is a quantitative, chemically specific technique with a probing depth of a few angstroms to a few nanometers. It is therefore ideally suited to investigate the chemical nature of the surfaces of catalysts. Because of the scattering of electrons by gas molecules, XPS is generally performed under vacuum conditions. However, for thermodynamic and/or kinetic reasons, the catalyst's chemical state observed under vacuum reaction conditions is not necessarily the same as that of a catalyst under realistic operating pressures. Therefore, investigations of catalysts should ideally be performed under reaction conditions, i.e., in the presence of a gas or gas mixtures. Using differentially pumped chambers separated by small apertures, XPS can operate at pressures of up to 1 Torr, and with a recently developed differentially pumped lens system, the pressure limit has been raised to about 10 Torr. Here, we describe the technical aspects of high-pressure XPS and discuss recent applications of this technique to oxidation and heterogeneous catalytic reactions on metal surfaces.

Book Description
Spectroscopy in Heterogeneous Catalysis deals with the applications of spectroscopy in heterogeneous catalysis. The concepts and capabilities of a particular technique, experimental procedures, and examples of all proven or potentially important applications are discussed. The use of spectroscopic measurements in guiding empirical approaches to applied problems and to fundamental studies of the chemical identity of catalytic surfaces is also described. This book is comprised of eight chapters and begins with a discussion on the scope of spectroscopy in catalysis and applications of spectroscopy to zeolite catalysts. The following chapters focus on infrared spectroscopy, with emphasis on the theory and interpretation of infrared spectra; Raman spectroscopy and the theory of the Raman effect; diffuse reflectance and photoacoustic spectroscopies; and Mössbauer spectroscopy. Electron spin resonance spectroscopy and nuclear magnetic resonance spectroscopy are also considered. The final chapter is devoted to X-ray photoelectron spectroscopy (XPS) and its application to core electrons, along with the experimental equipment and procedures used. The applications of XPS to studies of surface behavior and catalyst composition and chemistry are outlined. This monograph will be a useful resource for physicists, researchers, and potential researchers in heterogeneous catalysis.
