Metal Oxide Nanostructures as Gas Sensing Devices explores the development of an integrated micro gas sensor that is based on advanced metal oxide nanostructures and is compatible with modern semiconductor fabrication technology. This sensor can then be used to create a compact, low-power, handheld device for analyzing air ambience. The book first covers current gas sensing tools and discusses the necessity for miniaturized sensors. It then focuses on the materials, devices, and techniques used for gas sensing applications, such as resistance and capacitance variations. The author addresses the issues of sensitivity, concentration, and temperature dependency as well as the response and recovery times crucial for sensors. He also presents techniques for synthesizing different metal oxides, particularly those with nanodimensional structures. The text goes on to highlight the gas sensing properties of many nanostructured metal oxides, from aluminum and cerium to iron and titanium to zinc and zirconium. The final chapters deal with existing and future devices that are based on nanostructures. Miniaturized systems that analyze air ambience need sensors capable of identifying different gaseous species. Exploring state-of-the-art gas sensing devices, this book shows how nanostructured metal oxides are ideally suited for use as gas sensing elements.

1-D metal oxide nanostructures, especially those with semiconducting properties, have attracted much attention in recent years due to their potential and emerging applications, specifically in environment purification and energy devices. For these applications, there have been many efforts to grow 1-D nanostructures in the form of nanotubes, nanorods, and nanowires using processes that conserve energy, are cost effective, and can be scaled up for large-scale production. 1-Dimensional Metal Oxide Nanostructures gathers under one title the most recent development of oxide nanomaterials, especially those fabricated via oxidation process in the nanoscale field. Thermal and anodic oxidation processes are reviewed with an aim to offer an in-depth understanding of mechanisms of 1-D nanostructure formation, their characteristics, and limitations. Other more common methods are also discussed, including sol-gel, hydrothermal, and other templated methods. Important applications of 1-D nanostructures are then presented, focusing on oxides like zinc oxide, titanium oxide, zirconium oxide, copper oxide, and iron oxide. A chapter on carbon nanotubes hybrid with these oxides is also included as well as one on silicon oxide nanowires formation by local anodic oxidation process. Aimed at researchers, academics, and engineers working across the fields of nanotechnology, materials science, chemistry, physics, semiconductors, and environmental and biomedical engineering, this essential reference enables readers to grasp the main concepts of nanomaterials in 1-D: formation technique, characteristics, and uses. It also encourages practical innovations in nanotechnology, especially in curbing pressing global issues related to energy, environment, and security.

The goal of this thesis is the development of scalable, low cost synthesis of metal oxide nanostructures based electrodes and to correlate the chemical modifications with their energy conversion performance. Methods in energy conversion in this thesis have focused on two aspects; a potentiometric chemical sensor was used to determine the analytical concentration of some components of the analyte solution such as dopamine, glucose and glutamate molecules. The second aspect is to fabricate a photo-electrochemical (PEC) cell. The biocompatibility, excellent electro-catalytic activities and fast electron transfer kinetics accompanied with a high surface area to volume ratio; are properties of some metal oxide nanostructures that of a potential for their use in energy conversion. Furthermore, metal oxide nanostructures based electrode can effectively be improved by the physical or a chemical modification of electrode surface. Among these metal oxide nanostructures are cobalt oxide (Co3O4), zinc oxide (ZnO), and bismuth-zincvanadate (BiZn2VO6) have all been studied in this thesis. Metal oxide nanostructures based electrodes are fabricated on gold-coated glass substrate by low temperature (< 100 0C) wet chemicalapproach. X-ray diffraction, x-ray photoelectron spectroscopy and scanning electron microscopy were used to characterize the electrodes while ultraviolet-visible absorption and photoluminescence were used to investigate the optical properties of the nanostructures. The resultant modified electrodes were tested for their performance as chemical sensors and for their efficiency in PEC activities. Efficient chemically modified electrodes were demonstrated through doping with organic additives like anionic, nonionic or cationic surfactants. The organic additives are showing a crucial role in the growth process of metal oxide nanocrystals and hence can beused to control the morphology. These organic additives act also as impurities that would significantly change the conductivity of the electrodes. However, no organic compounds dependence was observed to modify the crystallographic structure. The findings in this thesis indicate the importance of the use of controlled nanostructures morphology for developing efficient functional materials.

Abstract: Abstract of thesis entitled FABRICATION AND CHARACTERIZATION OF METAL OXIDE NANOSTRUCTURES Submitted by Li Dan for the degree of Doctor of Philosophy at The University of Hong Kong in July 2007 Among various nanostructured materials, metal oxides are very promising for a variety of practical applications. Among different possible synthesis methods for metal oxide nanostructures, hydrothermal synthesis is of great interest because it is safe and environmentally friendly, and is typically performed at temperatures of less than 200 C. In this dissertation, several metal oxide nanostructures, including zinc oxide (ZnO), copper oxide (CuO) and nickel oxide (NiO) nanostructures, were fabricated by hydrothermal synthesis from aqueous solutions of zinc/copper/nickel nitrate hydrate and hexamethylenetetramine. The morphological, structural, optical and electrochemical properties of resultant nanostructures were studied by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffractometry (XRD), energy dispersive X-ray spectroscopy (EDX), photoluminescence (PL), and electron paramagnetic resonance spectroscopy (EPR). The obtained ZnO nanorods are straight and perpendicular to the substrate. The substrate conditions have considerable effects on the size and the orientation of the nanorods. The pH value of solutions also has significant influence on the morphology of resultant ZnO nanostructures. The PL spectra of the ZnO nanorods exhibit one UV peak and one yellow peak ( 578 nm). The ZnO nanorods also show very strong EPR signal at g 1.96. For different synthesis conditions, spherical assemblies of CuO platelets and CuO nanostructured films were obtained respectively. The solution concentration, pH value, synthesis temperature, and presence of seeds significantly affect obtained morphology as well as adhesion to the substrate. For different synthesis conditions, NiO nanowalls and NiO nanostructured films were obtained respectively. The influence of pH value is different on different NiO nanostructures. Finally, transition metal (Mn, Cr, and Co) doped ZnO nanostructures were synthesized by a hydrothermal method from aqueous solutions of zinc nitrate hydrate, TM (TM = Mn, Cr, Co) nitrate hydrate, and hexamethylenetetramine. The addition of TM nitrate hydrate resulted in the change of the shape and preferential orientation of ZnO nanorods. Also, the addition of the dopant affects the optical properties, including the ratio of UV to defect emission and the position of the UV emission peak.

The work covered herein discusses for the first time various techniques used in the fabrication of metal oxide nanofibers and nanotubes from eletrospun carbon fibers as templates. The nanofibers were prepared by electrospinning metal oxide precursor inside a polymer matrix. The metal oxide tubes were by tubes by fiber templating. This was followed by calcination to yield the nanofibers and nanotubes. Their morphological, structural, optoelectronic and catalytic properties are also discussed. Among key applications they have found utilization as catalyst supports. Palladium nanoparticles have been supported on Titanium dioxide nanofibers and applied in Heck-coupling reactions. Similarly, included is the effect of impurities on the metal oxide tubes properties done by doping with metal ions. In addition, photocatalytic behavior of metal oxides nanofibers have also been discussed.
