Book Synopsis On-Surface Synthesis II by : Dimas G. de Oteyza
Download or read book On-Surface Synthesis II written by Dimas G. de Oteyza and published by Springer. This book was released on 2018-03-19 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: On-surface synthesis is appearing as an extremely promising strategy to create organic nanoarchitectures with atomic precision. Molecular building blocks holding adequate functional groups are dosed onto surfaces that support or even drive their covalent linkage. The surface confinement and the frequent lack of solvents (most commonly being performed under vacuum conditions) create a completely new scenario fully complementary to conventional chemistry. In a pedagogical way and based on the most recent developments, this volume presents our current understanding in the field, addressing fundamental reaction mechanisms, synthetic strategies to influence the reactions according to our needs, as well as the ultimate growth and characterization of functional materials. Verging on chemistry, physics and materials science, the book is aimed at students and researchers interested in nanochemistry, surface science, supramolecular materials and molecular devices. Chapters "Mechanistic insights into surface-supported chemical reactions", "Reactivity on and of Graphene Layers: Scanning Probe Microscopy Reviels" and "Bottom-up fabrication of atomically precise graphene nanoribbons" of this book are available open access under a CC BY 4.0 license at link.springer.com

Book Synopsis Defects at Oxide Surfaces by : Jacques Jupille
Download or read book Defects at Oxide Surfaces written by Jacques Jupille and published by Springer. This book was released on 2015-02-09 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the basics and characterization of defects at oxide surfaces. It provides a state-of-the-art review of the field, containing information to the various types of surface defects, describes analytical methods to study defects, their chemical activity and the catalytic reactivity of oxides. Numerical simulations of defective structures complete the picture developed. Defects on planar surfaces form the focus of much of the book, although the investigation of powder samples also form an important part. The experimental study of planar surfaces opens the possibility of applying the large armoury of techniques that have been developed over the last half-century to study surfaces in ultra-high vacuum. This enables the acquisition of atomic level data under well-controlled conditions, providing a stringent test of theoretical methods. The latter can then be more reliably applied to systems such as nanoparticles for which accurate methods of characterization of structure and electronic properties have yet to be developed. The book gives guidance to tailor oxide surfaces by controlling the nature and concentration of defects. The importance of defects in the physics and chemistry of metal oxide surfaces is presented in this book together with the prominent role of oxides in common life. The book contains contributions from leaders in the field. It serves as a reference for experts and beginners in the field.
Book Synopsis Titanium Dioxide Photocatalysis by : Vladimiro Dal Santo
Download or read book Titanium Dioxide Photocatalysis written by Vladimiro Dal Santo and published by MDPI. This book was released on 2019-05-27 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the seminal work of Fujishima et al. dates back to 1971, TiO2 still remains the most diffused and studied semiconductor, employed in photo-oxidation processes for cleantech (i.e., polluted water and air treatment), in solar fuel production (mainly hydrogen production by water photo splitting), and in Carbon Capture and Utilization (CCU) processes by CO2 photoreduction. The eleven articles, among them three reviews, in this book cover recent results and research trends of various aspects of titanium dioxide photocatalysis, with the chief aim of improving the final efficiency of TiO2-based materials. Strategies include doping, metal co-catalyst deposition, and the realization of composites with plasmonic materials, other semiconductors, and graphene. Photocatalysts with high efficiency and selectivity can be also obtained by controlling the precise crystal shape (and homogeneous size) and the organization in superstructures from ultrathin films to hierarchical nanostructures. Finally, the theoretical modeling of TiO2 nanoparticles is discussed and highlighted. The range of topics addressed in this book will stimulate the reader’s interest as well as provide a valuable source of information for researchers in academia and industry.

Book Synopsis Tuning electronic properties of transition metal oxides at nanoscale by means of redox processes by : Karol Cieslik
Download or read book Tuning electronic properties of transition metal oxides at nanoscale by means of redox processes written by Karol Cieslik and published by Karol Cieslik. This book was released on with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The climate crisis that we are facing has galvanized the scientific and engineering communities and has led to the rapid development of new, efficient, environmentally-friendly devices. One of the most promising classes of materials for such applications are transition metal oxides. This is due to the fact that by controlling the oxygen content in these crystals by means of reduction and oxidation, the material properties can be tuned in a wide range of values. Thus, the transition metal oxides, such as the model crystals, titanium dioxide (TiO2) and strontium titanate (SrTiO3), find use in so many different fields, from photocatalysis, to energy storage (solid oxide fuel cells), information technology (memristors) and even healthcare (antibacterial films). This PhD thesis is an investigation into the effect of reduction and oxidation on the electronic properties of transition metal oxides. These processes were studied at nanoscale using a multitude of techniques to provide a thorough characterization of the changes that occur in the studied systems, i.e. TiO2 and SrTiO3. Moreover, the experiments were performed in both ultra high vacuum (UHV) conditions, as well as in oxygen, and even in atmospheric air, in order to comprehensively describe the changes in properties and to bring the results closer to applications. The goal of the dissertation was to study the evolution of the electronic properties, i.e. the work function and conductivity, due to redox processes, and to add to the general understanding of these processes. The experiments revealed that the electronic properties may be tuned. In case of using reduction by means of annealing in UHV, ion sputtering, and repeated ion sputtering and annealing, and for oxidation by exposure to oxygen or air at room temperature, and annealing in oxygen. Using this range of methods, the conductivity of TiO2 can be changed from semiconductive-like to metallic-like. Furthermore, the work function of the transition metal oxides can be tuned in a wide range, from 3.4 eV to 5.0 eV for TiO2, and from 2.9 eV to 4.5 eV for SrTiO3. This is associated with changes in surface and subsurface composition, crystallography, morphology and even with the growth of new oxide phases. The key findings in the field of surface science were the description of the changes in electronic properties due to repeated sputtering and annealing, and the presence of oxygen getter substances. These results are important, because they touch upon the very basis of every experiment in the field, i.e. the preparation of crystals. This work can be used to foster greater reproducibility of experiments, as well to provide new means of designing experiments. Another object of the study was the technologically interesting system of conductive nanowires on semiconductive SrTiO3 substrate. It was shown that the nanostructures are composed of a TiO core covered with a layer of Ti3O5. The evolution of the system, starting from atomically flat strontium titanate, through nanowire-covered substrate to a crystal with a layer of porous titanium suboxides was described. The effect of annealing in oxygen on wire-covered surface was been investigated.

Book Synopsis Nanophotocatalysis and Environmental Applications by : Inamuddin
Download or read book Nanophotocatalysis and Environmental Applications written by Inamuddin and published by Springer. This book was released on 2019-03-29 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents photocatalysis as a state-of-art technology in energy production and conversion. The ever increasing demand for energy with growing economies has led to a dearth of energy sources. The exhaustive dependability on non-renewable resources of energy has not just depleted them but also lead to the birth of secondary problems such as pollution and climate change. The photoactive processes have opened a new window for the production of green energy and helped in environmental sustainability. The harnessing of renewable sources especially sun and water for fuel production and noxious gases reduction solve both the issues of pollution mitigation and energy crisis.
