High-Resolution XAS/XES Analyzing Electronic Structures of Catalysts
Coordonnateur : Sa Jacinto
Photon-in-photon-out core level spectroscopy is an emerging approach to characterize the electronic structure of catalysts and enzymes, and it is either installed or planned for intense synchrotron beam lines and X-ray free electron lasers. This type of spectroscopy requires high-energy resolution spectroscopy not only for the incoming X-ray beam but also, in most applications, for the detection of the outgoing photons. Thus, the use of high-resolution X-ray crystal spectrometers whose resolving power ?E/E is typically about 10?4, is mandatory.
High-Resolution XAS/XES: Analyzing Electronic Structures of Catalysts covers the latest developments in X-ray light sources, detectors, crystal spectrometers, and photon-in-photon-out core level spectroscopy techniques. It also addresses photon-in-photon-out core level spectroscopy applications for the study of catalytic systems, highlighting hard X-ray measurements primarily due to probe high penetration, enabling in situ studies.
This first-of-its-kind book:
- Discusses high-resolution X-ray emission spectroscopy (XES) and X-ray absorption spectroscopy (XAS) in terms of time-resolved and surface enhancement
- Supplies an understanding of catalytic reactivity essential for capitalizing on core level X-ray spectroscopy at fourth-generation light sources (XFELs)
- Describes all spectrometers developed to perform core level X-ray spectroscopy, considering the advantages and disadvantages of each
- Details methods to elucidate aspects of catalysts under working conditions, such as active sites and molecule adsorption
- Introduces theoretical calculations of spectra and explores biological as well as heterogeneous catalysts
Complete with guidelines and warnings for the use of this type of spectroscopy, High-Resolution XAS/XES: Analyzing Electronic Structures of Catalysts provides a comprehensive overview of the current state of this exciting field.
