Metal Oxides in Supercapacitors addresses the fundamentals of metal oxide-based supercapacitors and provides an overview of recent advancements in this area. Metal oxides attract most of the materials scientists use due to their excellent physico-chemical properties and stability in electrochemical systems. This justification for the usage of metal oxides as electrode materials in supercapacitors is their potential to attain high capacitance at low cost. After providing the principles, the heart of the book discusses recent advances, including: binary metal oxides-based supercapacitors, nanotechnology, ternary metal oxides, polyoxometalates and hybrids. Moreover, the factors affecting the charge storage mechanism of metal oxides are explored in detail. The electrolytes, which are the soul of supercapacitors and a mostly ignored character of investigations, are also exposed in depth, as is the fabrication and design of supercapacitors and their merits and demerits. Lastly, the market status of supercapacitors and a discussion pointing out the future scope and directions of next generation metal oxides based supercapacitors is explored, making this a comprehensive book on the latest, cutting-edge research in the field. Explores the most recent advances made in metal oxides in supercapacitors Discusses cutting-edge nanotechnology for supercapacitors Includes fundamental properties of metal oxides in supercapacitors that can be used to guide and promote technology development Contains contributions from leading international scientists active in supercapacitor research and manufacturing

In this dissertation, a materials processing method to prepare high surface area solid oxide fuel cell (SOFC) scaffolds at traditional sintering temperatures (1000°C–1400°C) was developed. We named this method "in situ carbon templating" and have used it to improve the performance of SOFC electrodes. There are two key differences between the in situ carbon templating and the traditional SOFC scaffold fabrication methods. First, the traditional method uses mixtures of metal oxides and carbon pore formers while in situ carbon templating uses hybrid materials. Second, in the traditional method, green scaffolds are sintered directly in air while, in the in situ carbon templating method, sintering is undertaken under inert atmospheres followed by calcination in air at low temperatures (~700°C). In the traditional method, the carbon pore formers are oxidized away at ~900°C which leaves the metal oxide particles with nothing to keep them apart. In the in situ carbon templating method, however, the organic component of the hybrid material is pyrolyzed during sintering under inert atmospheres which leaves behind an amorphous carbon template. This carbon template remains throughout the entire sintering period which keeps the metal oxide particles apart. This carbon template is removed by a subsequent calcination in air which takes a place at a temperature too low to cause significant material coarsening. Many high surface area SOFC materials were prepared including yttria-stabilized zirconia (YSZ, Zr[subscript 0.92]Y[subscript 0.16]O[subscript 2.08]), gadolinia doped ceria (GDC, Gd[subscript 1-x]Ce[subscript x]O2), samaria doped ceria (SDC, Sm[subscript 1-x]Ce[subscript x]O2), lanthanum strontium cobalt ferrite (LSCF, La[subscript 1-x]Sr[subscript x]Co[subscript 1-y]Fe[subscript y]O3), and strontium titanate (STO, SrTiO3). In all cases, the surface area of the materials prepared via in situ carbon templating were at least 40 times higher than those prepared via traditional methods. The impact of incorporating high surface area materials into SOFC electrodes through in situ carbon templating was also assessed. Thus far, incorporating high surface area YSZ into SOFC cathodes reduced the non-ohmic resistance by ~40% at 550°C. In the future, more experiments will be conducted to assess whether further electrode performance improvements could be achieved with various SOFC electrodes.

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.

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.
