The author provides a unified account of the electrochemical material science of metal chalcogenide (MCh) compounds and alloys with regard to their synthesis, processing and applications. Starting with the chemical fundamentals of the chalcogens and their major compounds, the initial part of the book includes a systematic description of the MCh solids on the basis of the Periodic Table in terms of their structures and key properties. This is followed by a general discussion on the electrochemistry of chalcogen species, and the principles underlying the electrochemical formation of inorganic compounds/alloys. The core of the book offers an insight into available experimental results and inferences regarding the electrochemical preparation and microstructural control of conventional and novel MCh structures. It also aims to survey their photoelectrochemistry, both from a material-oriented point of view and as connected to specific processes such as photocatalysis and solar energy conversion. Finally, the book illustrates the relevance of MCh materials to various applications of electrochemical interest such as (electro)catalysis in fuel cells, energy storage with intercalation electrodes, and ion sensing.

This is a handy textbook comprised of chapters introducing the fundamentals of chalcogen chemistry with a focus on chalcogens and selected derived compounds and/or materials with illustrative practical applications. These low-valent chemistry elements of Group 16 or group VI- in the modern periodic table include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po), and they exhibit extremely interesting properties. They are endowed with supramolecular and structure bonding reactivities that allow them to form a variety of new compounds with sophisticated characteristics, thus making their way into a new era of materials development. It is hoped that readers of this textbook with a general background knowledge in chemistry, biogeochemistry, biochemistry, biology, food, agriculture, and also medicine, as well as pharmacy, will find the chapters enriching in new knowledge. An introductory chapter orients readership in this particular field of chemistry with a summative focus on the multidisciplinary approach employed in the compilation of the chapters. As such, the text is suitable for scientists, technologists, students, as well as those whose major interest is chalcogen chemistry, with particular interests in the chalcogen compounds and materials.

Up until a few decades ago, chalcogen chemistry was mainly represented by the chemistry of sulfur-containing compounds. However, with the rise in research around selenium and tellurium compound chemistry, the field has developed significantly as it continues to uncover and understand the peculiarities chalcogens exhibit. Taking an introductory approach, this book is the foundation to the subject that has been long needed. Covering organic and inorganic synthesis, structural properties, coordination chemistry and computational modelling, all key classes of chalcogen compounds are illustrated. Applications across materials science, biology, pharmaceutical science and environmental topics highlight to readers the impact of chalcogen chemistry in many aspects of research. Edited by international leaders in the field, Chalcogen Chemistry brings together contributions from acclaimed researchers around the world. This book is ideal for newcomers and established researchers, and provides the first building block to uncovering this fascinating field.

This thesis has its focus on the chemistry and physical properties of normal valence and hypervalent polar chalcogenides (PCs). The motivation for this study lies in the synthesis of new compounds with complex crystal structures. It aims at understanding the relationship between crystal structure, chemical bonding and physical properties through experimental and theoretical analyses. PCs are of special interest since they are at the interface between metals and nonmetals. The chemistry at this interface is governed by the interplay between covalent, metallic and ionic bonding, which makes it interesting and challenging to understand the relationship between crystal structure and chemical bonding. The main reason for aiming at structural complexity is to target new materials with low thermal conductivities - a key requirement for efficient thermoelectric materials. Thermoelectrics are capable of converting waste heat into electricity, which is of considerable economic and environmental interest. Previous discoveries of efficient, chalcogenide-based thermoelectrics such as PbTe, Bi2Te3, CsBi4Te6 and superionic Cu2-xSe motivated the exploratory search for new Cu- and Pn-chalcogenides (Pn = Sb, Bi) and to study related materials such as BaBiTe3 (cf. chapter V). One route towards complex crystal structures is to use a charge transfer from cations such as Sr or Ba to an anionic framework in order to create complex anionic, covalent networks (e.g. channels or layers) which can lead towards interesting physical properties. Stereoactive lone pairs can increase the structural complexity through distortions of the coordination polyhedra, which is one reason for studying systems containing Pn atoms such as Sb and Bi. Probing the physical properties and studying the crystal structure and chemical bonding of both, new and known polar chalcogenides with complex crystal structures resulted in interesting new discoveries, i.e. new compounds and crystal structures as well as unexpected physical properties. The thesis is separated in normal valence compounds, which can be entirely described by classical two-center two-electron (2c-2e) bonds (i.e. where the electrons are fully localized) and those, which contain hypervalent bonds and networks in which the electrons are partially delocalized. It contains four main parts: the study of 1) A0.5CuZrSe3 et ACuYSe3 (A = Sr, Ba) belonging to a family of compounds known as the "1113 family", 2) Ba2FePnSe5 (Pn = Sb, Bi), 3) Ba4Cu8Se13 and 4) BaBiTe3-xSex (x = 0, 0.05, 1 and 3).

The earliest experimental data on an oxygen-free glass have been published by Schulz-Sellack in 1870 [1]. Later on, in 1902, Wood [2], as well as Meier in 1910 [3], carried out the first researches on the optical properties of vitreous selenium. The interest in the glasses that exhibit transparency in the infrared region of the optical spectrum rose at the beginning of the twentieth century. Firstly were investigated the heavy metal oxides and the transparency limit was extended from (the case of the classical oxide glasses) up to wavelength. In order to extend this limit above the scientists tried the chemical compositions based on the elements of the sixth group of the Periodic Table, the chalcogens: sulphur, selenium and tellurium. The systematic research in the field of glasses based on chalcogens, called chalcogenide glasses, started at the middle of our century. In 1950 Frerichs [4] investigated the glass and published the paper: “New optical glasses transparent in infrared up to 12 . Several years later he started the study of the selenium glass and prepared several binary glasses with sulphur [5]. Glaze and co-workers [6] developed in 1957 the first method for the preparation of the glass at the industrial scale, while Winter-Klein [7] published reports on numerous chalcogenides prepared in the vitreous state.

The Handbook of Chalcogen Chemistry: New Perspectives in Sulfur, Selenium and Tellurium provides an overview of recent developments, particularly from the last decade, on the chemistry of the chalcogen group elements (S, Se and Te). While up to a few decades ago, chalcogen chemistry was mainly centred on sulphur, in recent years the research based on Se and Te has increased dramatically, and has created huge scope for the use of compounds based on this type of chemistry. The Handbook is organised into two parts, the first of which deals systematically with the chemistry of chalcogens in relation to other group elements in the periodic table. It also includes an overview of metal-chalcogenides and metal-polychalcogenides. The second part reflects the interdisciplinary nature of chalcogen chemistry and focuses on biological, materials and supramolecular aspects of the field. This Handbook gives a comprehensive overview on recent developments over the last decade and is ideal for researchers in the field.
