N4 Macrocyclic Metal Complexes

In response to significant developments in sensor science and technology, this book offers insight into the various extended applications and developments of N4 macrocycle complexes in biomimetic electrocatalysis. Chapters are devoted to the chemistry, electronic and electrochemical properties of porphyrin- based polymetallated supramolecular redox catalysts and their applications in analytical and photoelectrochemical molecular devices; the use of porphyrins, phthalocyanines and related complexes as electrocatalysts for the detection of a wide variety of environmentally polluting and biologically relevant molecules; and the use of electropolymerized metalloporphyrin and metallophthalocyanine films as powerful materials for analytical tools, especially for sensing biologically relevant species.

This new edition describes the state of the art regarding molecular catalysts such as MN4 metal complexes, like porphyrins and phthalocyanines. This volume focuses on the particular case of the electrocatalysis of the reduction of O2 for practical applications in fuel cells and air batteries. Indeed, active and stable materials have been developed in the last 5 years where MN4 catalytic systems can be obtained by the pyrolysis of starting materials that do not necessarily involve MN4 complexes. These latter systems constitute a new class of stable and highly active non-precious metal catalysts for ORR that can replace expensive Platinum containing electrodes. The book also offers future projections and points out new fields of research and development of these non-precious metal catalysts.

This new edition describes the state of the art regarding metal complexes of N4-ligands, such as porphyrins and phthalocyanines. Volume 2 focuses on the electro assisted use of N4 complexes as biomimetic models for studying several biological redox processes. It focuses on molecular oxygen transport and catalytic activation to mimic monooxygenase enzymes of the cytochrome P450 in particular. It also examines N4 complexes’ use as catalysts for the oxidative degradation of various types of pollutants (organo-halides, for example) and residual wastes. The remarkable activity of these complexes towards a large number of significantly relevant biological compounds makes them excellent candidates as electrode modifiers for electrochemical sensing. This volume also discusses applications of N4 Macrocyclic Metal Complexes to photoelectrochemistry and photocatalysis, and concludes with an exciting section on Electrosynthesis of N4.

Coordination compounds have been well-known for their wide variety of applications for over a century, as well as enhancing the researcher’s interest and concern in evaluating their action mechanism. It is certainly one of the most intensely discussed research topics. Coordination compounds involve different metal-ion-ligand phenomenon. The involved metal ions play a significant role in structural association and functioning of several processes in the genetic and metabolism system. In recent years, Schiff base ligands have gained significant interest and received a keen interest of many researchers. Schiff’s base ligands have been recognized to hold a wide variety of biological and medicinal activities due to the presence of donor atoms. They have proved exceptional pharmalogical actions such as antimicrobial, anti-tuberclosis, antiplatelet, antidiabetic, antiarthritis, antioxidant, anti-inflammatory, anticancer, antiviral, antimalarial, and analgesic. These biologically active Schiff base ligands have also been shown to inhibit enzyme mobilization and, when bound to a metal ion, exhibit enhanced biological activity, making them useful in a number of fields. As a result, metal complexes of Schiff base ligands are gaining popularity due to their unique properties and functionalities. Schiff base complex-based research for educational and industrial purposes is booming, and the number of publications is gradually increasing. Despite these interests, there is currently no detailed book on Schiff base metal complexes that covers the structures, biological activities, and other non-biological perspectives. This book delves into the structures of Schiff base metal complexes, which are critical in assessing the biological viability of any complex. It also highlights their biological significance in pharma and drug discovery like antibacterial, antifungal, anticancer, anti-inflammatory, anti-arthritis, anti-diabetic, antioxidants, anti-proliferative, antitumor, anticancer, antiviral. The fundamentals of metal complexes are described, as well as an up-to-date outline of developments in synthesis, characterization methods, properties- chemical, thermal, optical, structural, and applications. This book also discusses the other applications of Schiff base metal complexes: as sensor (luminescent, electrochemical, and biosensor), as pigments in dying and paint industries, as photocatalyst to improve the degradation rate. Features : This book would be useful for academia, researchers and engineers working in the area of Schiff base and their metal complexes. This book will give an in-depth account of the properties of Schiff base and their metal complexes. This book will discuss the details of synthesis methods for Schiff base and their metal complexes. This book will cover emerging trends in the use of Schiff base metal complexes in the industry. This book will provide an overview of the wider biological applications of Schiff base metal complexes

The book "Redox" provides vast insight into the oxidation-reduction reactions to its readers. The book consists of three sections that include redox in the coordination compounds, organic compounds and polymerization; redox in electrochemistry; and redox and fish welfare. The first section consists of three chapters that describe the role of redox reactions in several fields such as transition metal chemistry, degradation processes of toxic compounds and dyes in treatment of water and wastewater, the catalysis of oxidation of organic compounds by metal active sites, and synthesis of copolymers. The second section consists of two chapters. The role of redox reactions and reactivity description of compounds are discussed in the second section of the book. The non-aqueous redox flow batteries are described in this section. The third section extensively discusses the redox balance and fish welfare and consists of one chapter.

This book updates the latest advancements in new chemistries, novel materials and system integration of rechargeable batteries, including lithium-ion batteries and batteries beyond lithium-ion and addresses where the research is advancing in the near future in a brief and concise manner. The book is intended for a wide range of readers from undergraduates, postgraduates to senior scientists and engineers. In order to update the latest status of rechargeable batteries and predict near research trend, we plan to invite the world leading researchers who are presently working in the field to write each chapter of the book. The book covers not only lithium-ion batteries but also other batteries beyond lithium-ion, such as lithium-air, lithium-sulfur, sodium-ion, sodium-sulfur, magnesium-ion and liquid flow batteries.

The increase of greenhouse gases in the atmosphere and the decrease of the available amount of fossil fuels necessitate finding new alternative and sustainable energy sources in the near future. This book summarizes the role and the possibilities of catalysis in the production of new energy carriers and in the utilization of different energy sources. The main goal of this work is to go beyond those results discussed in recent literature by identifying new developments that may lead to breakthroughs in the production of alternative energy. The book discusses the use of biomass or biomass derived materials as energy sources, hydrogen formation in methanol and ethanol reforming, biodiesel production, and the utilization of biogases. Separate sections also deal with fuel cells, photocatalysis, and solar cells, which are all promising processes for energy production that depend heavily on catalysts.
