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.

Advanced materials and nanotechnology is a promising, emerging field involving the use of nanoparticles to facilitate the detection of various physical and chemical parameters, including temperature, humidity, pH, metal ion, anion, small organic or inorganic molecules, gases, and biomolecules responsible for environmental issues that can lead to diseases like cancer, diabetes, osteoarthritis, bacterial infections, and brain, retinal, and cardiovascular diseases. By monitoring environmental samples and detecting these environmental issues, advanced nanotechnology in this type of sensory technology is able to improve daily quality of life. Although these sensors are commercially available for the detection of monovalent cations, anions, gases, volatile organic molecules, heavy metal ions, and toxic metal ions, many existing models require significant power and lack advanced technology for more quality selectivity and sensitivity. There is room in these sensors to optimize their selectivity, reversibility, on/off ratio, response time, and their environmental stability in real-world operating conditions. This book explores the methods for the development and design of environmentally-friendly, simple, reliable, and cost effective electrochemical nanosensors using powerful nanostructured materials. More specifically, it highlights the use of various electrochemical-based biosensor sensors involved in the detection of monovalent cations, anions, gases, volatile organic molecules, heavy metal ions, and toxic metal ions, with the ultimate goal of seeing these technologies reach market.

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.
