Download or read book An X Ray Photoelectron Spectroscopy Study of Multilayered Transition Metal Carbides MXenes written by Joseph Halim and published by . This book was released on 2016 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, a new family of two-dimensional (2D) early transition metal carbides and carbonitrides, labeled MXenes, was discovered at Drexel University. MXenes are produced by selectively etching mostly Al from Al-containing MAX phases and replacing Al with surface termination groups. Theoretically it has been predicted that changing the nature of the surface terminations, T, can change MXenes' properties, such as electronic and optical, resulting in changes in performance in various applications such as electrodes for Li-ion batteries. Prior to this work, there had been little systematic effort devoted to carefully identifying and quantifying the exact nature of T. In this work, high resolution XPS spectra of multilayered Ti3C2Tx, Ti2CTx, Ti3CNTx, Nb2CTx, Nb4C3Tx, V2CTx, Mo2CTx, Mo2TiC2Tx, and Mo2Ti2C2Tx were acquired and analyzed. The influence of the M and X elements, the order of MXene, n, aging, Ar+ sputtering, and the concentration/nature of the etchants on the amounts of -O, -OH and -F, were systematically investigated. XPS analysis confirmed the intercalation of Li+ ions upon etching Ti3AlC2 using a mixture of LiF and HCl or LiCl and HF; when Ti3C2Tx multilayers is immersed in RbCl or NaCl solutions, cation exchange resulted in the replacement of Li+ ions with Rb+ or Na+, respectively. Similar cation intercalations were confirmed when treating HF-etched Ti3C2Tx samples with Ti3C2Tx with alkali metal hydroxides, such as NaOH and KOH. Based on quantification of the various chemical species before and after treatment, a mechanism was suggested where the reduction of -F terminations took place by exchanging with -OH and -O terminations and/or complete removal of Ti-F species and converting them to TiO2-Fx. From XPS peak fits for all MXene samples in this study, it was established that x was ~ 2.0±0.2. Both -F and -OH terminations are formed during etching through the reaction of MXene with HF or H2O, respectively. However, for the -O terminations to form, a mechanism was suggested were some of the -OH terminations dissociate into -O termination and H+, where the latter reacts with an intercalated H2O forming [H3O]+. The latter are then replaced with cations via ion exchange. This reaction has been suggested based on the trend that, for most MXenes analyzed, the ratio between -O terminations and adsorbed water plus cations is equal to unity or lower, suggesting that all H+ that dissociates from the -O terminations reacts with H2O molecules to form H3O+. Only five compounds out of the sixteen studied were found not to follow this trend (in those cases the ratio was higher than unity) where further investigation is needed to determine the cause of this anomaly. Given that recent work reported that the average oxidation state of Ti in Ti3C2Tx is + 2.4, the average oxidation state of C - for 8 different samples - was determined to be ~ -2.6±0.1. It is thus reasonable to conclude that the average oxidation states of Ti and C in Ti3C2Tx are weakly dependent on the etching conditions and/or intercalated cations. Similarly, the average oxidation state of C - for 2 different samples - was determined to be ~ -3.96±0.2 assuming the oxidation state of V determined in recent work to be +3.0. Based on this work, it is now possible to quantify the nature of the surface terminations in MXenes; information that can, in turn, be used to better design and tailor these novel 2D materials for various applications.

Download or read book Applications Of X ray Photoelectron Spectroscopy To Catalytic Studies From Routine Analysis To Cutting edge Surface Characterization written by Spyridon Zafeiratos and published by World Scientific. This book was released on 2023-07-04 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.The objective of this 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. Finally, the book describes relatively recent developments of this method for cutting-edge surface characterization mainly using synchrotron X-ray radiation.

Download or read book Proceedings of the 11th International Conference on Vacuum Ultraviolet Radiation Physics written by T. Miyahara and published by Elsevier. This book was released on 2012-12-02 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: These volumes contain 365 of the 505 papers presented at the VUV-11 Conference, held at Rikkyo University, Tokyo, from August 27th to September 1st 1995. The papers are divided into three sections: atomic and molecular spectroscopy, solid state spectroscopy and instrumentation and technological applications. New aspects presented were both quantitative and qualitative improvements in fluorescence spectroscopy and magnetic circular dichroism measurements. The fluorescence data are complementary to those of photoemission in a sense but they appear to open up a new method to analyze the optical excitation and relaxation processes. The application of magnetic circular dichroism has proved to be useful not only in analyzing the electronic structures of magnetic materials but also in practical applications to material engineering as found in experiments combined with photoelectron microscopy. Excellent developments in applications are only found in the field of surface photochemistry, where the technique of etching using VUV light has been appreciably refined. Although the majority of distinctive scientific features in the VUV-11 Conference have been brought about by the application of synchrotron radiation, experiments using a different type of light source appear to have progressed steadily. This is evident in the studies of plasma radiation.
Download or read book Synchrotron Light Sources and Free Electron Lasers written by Eberhard J. Jaeschke and published by Springer. This book was released on 2016-05-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardly any other discovery of the nineteenth century did have such an impact on science and technology as Wilhelm Conrad Röntgen’s seminal find of the X-rays. X-ray tubes soon made their way as excellent instruments for numerous applications in medicine, biology, materials science and testing, chemistry and public security. Developing new radiation sources with higher brilliance and much extended spectral range resulted in stunning developments like the electron synchrotron and electron storage ring and the freeelectron laser. This handbook highlights these developments in fifty chapters. The reader is given not only an inside view of exciting science areas but also of design concepts for the most advanced light sources. The theory of synchrotron radiation and of the freeelectron laser, design examples and the technology basis are presented. The handbook presents advanced concepts like seeding and harmonic generation, the booming field of Terahertz radiation sources and upcoming brilliant light sources driven by laser-plasma accelerators. The applications of the most advanced light sources and the advent of nanobeams and fully coherent x-rays allow experiments from which scientists in the past could not even dream. Examples are the diffraction with nanometer resolution, imaging with a full 3D reconstruction of the object from a diffraction pattern, measuring the disorder in liquids with high spatial and temporal resolution. The 20th century was dedicated to the development and improvement of synchrotron light sources with an ever ongoing increase of brilliance. With ultrahigh brilliance sources, the 21st century will be the century of x-ray lasers and their applications. Thus, we are already close to the dream of condensed matter and biophysics: imaging single (macro)molecules and measuring their dynamics on the femtosecond timescale to produce movies with atomic resolution.
