This thesis examines electrode materials such as mesoporous carbons, manganese oxides, iron oxides and their nanohybrids with graphene. It also explores several of the key scientific issues that act as the governing principles for future development of supercapacitors, which are a promising class of high-efficiency energy storage devices for tackling a key aspect of the energy crisis. However, critical technical issues, such as the low energy density and reliability, need to be addressed before they can be extended to a wide range of applications with much improved performance. Currently available material candidates for the electrodes all have their disadvantages, such as a low specific capacitance or poor conductivity for transition metal oxide/hydroxide-based materials. This thesis addresses these important issues, and develops a high-performance, flexible asymmetric supercapacitor with manganese oxides/reduced graphene oxide as the positive electrode and iron oxide/reduced graphene oxide as the anode, which delivers a high energy density of 0.056 Wh cm-3.
Описание: This book examines the electronic structure of earth-abundant and environmentally friendly materials for use as absorber layers within photovoltaic cells. The corroboration between high-quality photoemission measurements and density of states calculations yields valuable insights into why these materials have demonstrated poor device efficiencies in the vast literature cited. The book shows how the materials’ underlying electronic structures affect their properties, and how the band positions make them unsuitable for use with established solar cell technologies. After explaining these poor efficiencies, the book offers alternative window layer materials to improve the use of these absorbers. The power of photoemission and interpretation of the data in terms of factors generally overlooked in the literature, such as the materials’ oxidation and phase impurity, is demonstrated. Representing a unique reference guide, the book will be of considerable interest and value to members of the photoemission community engaged in solar cell research, and to a wider materials science audience as well.

Metal oxide nanomaterials exhibit interesting electrical and photochemical properties because of their size, stability, and high surface area that render them as great choices in fabricating alternative electrode materials for electrochemical energy storage and sensor applications. The hybridization of metal oxides with other materials lead to the improvement in electrical conductivity, stability, and electron transfer kinetics during the electrocatalytic reactions. These key factors result in greater sensitivity of the sensor materials towards the analyte molecules.
This book reviews the electrochemical determination of a variety of toxic chemical contaminants using metal oxide-based nanocomposite materials. Ultrasensitive and selective detection of toxic chemical contaminants is important and demanding, especially for monitoring and controlling environmental pollution. In recent years, metal oxide-based nanocomposite materials have shown high potential in the electrochemical detection of heavy metals, inorganic anions, phenolic compounds, pesticides, and chemical warfare reagents. Metal Oxides in Nanocomposite-Based Electrochemical Sensors for Toxic Chemicals comprehensively reviews this topic.
In addition to the instrumental simplicity, the electrochemical methods show the improved sensor performance through the synergetic effect of metal oxide and other electroactive nanomaterial present in the nanocomposite. Thus, detailed information on the electrochemical sensing of toxic chemical contaminants using metal oxide-based nanomaterials are discussed. The recent progress in developing electrochemical sensors using metal oxide-based nanocomposite materials and perspectives on future opportunities in sensor research and development are addressed in the book.

Описание: Gas Sensors based on Conducting Metal Oxides: Basic Understanding, Technology and Applications focuses on two distinct types of gas sensors based on conducting metal oxides. Ion conduction, applied in so-called solid-state electrolytic sensors for one, and electronic conduction used in semiconductivity gas sensors for the other. The well-known λ-probe, a key component to optimize combustion in car engines, is an example of the former type, and the in-cabin car air-quality control SnO2 and WO2 sensor array stands for the semiconductivity type. Chapters cover basic aspects of functioning principles and describe the technologies and challenges of present and future sensors.
Provides reader background and context on sensors, principles, fabrication and applications
Includes chapters on specific technological applications, such as exhaust sensors, environmental sensors, explosive gases alarms and more
Presents a structured presentation that allows for quick reference of vital information
