This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Considering the increasing energy and environmental problems associated with the exhaustible fossil fuels, renewable energy conversion devices have attracted tremendous attention, which hold the promise to supply the fuel and electricity in a sustainable way. For many of these devices, such as batteries, fuel cells, solar cells and solar water splitting cells, metal oxides are very important functional materials due to their earth abundance, good stability and diverse properties. Recently nanowire-based metal oxides have enabled revolutionary advances in various energy conversion devices, because of their unique physical and chemical properties resulting from the high aspect ratio and large surface area. Despite their advantages, practical applications of metal oxide nanowires are hindered, as conventional synthesis methods have limitations for large scale production. Flame synthesis can potentially solve this large-scale production issue for metal oxide nanowires, given its demonstrated scalability in the industrial production of nanoparticles. However, only until very recently has flame synthesis been applied to metal oxide nanowires. More research is needed to develop advanced flame synthesis method for metal oxide nanowires, to understand the mechanism to well control the size, shape and compositions for reliable manufacture, and to evaluate their quality and functionalities in real devices. This thesis presents a novel flame vapor deposition method for the synthesis of metal oxide nanowires with the capabilities of rapid rate, good uniformity over large area and broad substrate choice. Through the investigation of growth mechanism, good control over the morphology and composition was achieved by tuning the process parameters such as fuel/air ratio, source temperature, substrate material and temperature. In addition to synthesis, flame-based doping method (sol-flame doping) was innovated for controllable doping of metal oxide NWs to modify the properties of host materials at the nanometer scale. This sol-flame doping method not only preserves the morphology and crystallinity of the host NWs, but also allows fine control over the dopant concentration by simply varying the concentration of dopant precursor solution. With this method, significant enhancement of the electrocatalytic activity towards oxygen evolution reaction was achieved for TiO2 NWs (up to 760 mV reduction of the overpotential), attributing to simultaneously improved surface charge transfer kinetics and increased bulk conductivity by doping. Finally, the flame-synthesized metal oxide nanowires were implemented as a photoanode in photoelectrochemical water splitting. By rational design and scalable fabrication, the WO3/BiVO4/Ni:FeOOH composite nanowire photoanode generated a high photocurrent of 4.5 mA/cm2 at a potential of 1.23 VRHE under simulated sunlight, which is among the highest produced by any WO3/BiVO4 based photoanodes. With the demonstrated rapid rate, good controllability and superior performance of the flame-produced metal oxide nanowires, these flame synthesis and doping methods can potentially enable future generation of energy devices by removing the barrier for large-scale production of tailored metal oxide nanowires.

Available in PDF, EPUB and Kindle. Book excerpt: Herein, two novel methods for the flame synthesis of metal oxide nanowire arrays and related nanomaterials are developed and investigated. Both methods are rapid (micrometer/minute axial growth rate), atmospheric, controllable and scalable, and result in highly pure and crystalline materials. Simultaneously, these methods allow the growth of metal oxide nanowires on diverse, technologically relevant, and often delicate substrates. The first method is flame-heated solid phase diffusion growth, in which a metal substrate is rapidly heated to high temperatures by a flame, and metal oxide nanowires grow by metal diffusion out of the substrate in the hot, oxidative post-flame environment. The second is flame vapor deposition, in which the flame oxidizes and evaporates metals at high temperatures to produce large concentrations of oxide vapors that condense onto cooler substrates in the form of nanowires and other nanostructures. In each method, the chemical composition, growth rate and morphology (shape, packing density and alignment) of the nanostructures can be finely controlled by tuning flame parameters such as the fuel/air ratio and temperature, and substrate parameters such as surface energy and temperature. Moreover, an application of flame synthesized nanowires is demonstrated for the first time. As a result of superior morphology (increased length and packing density), the photoelectrochemical water-splitting performance of flame-synthesized tungsten trioxide nanowires is more than twice that of state of the art tungsten trioxide nanowire photoanodes synthesized by conventional hydrothermal and vapor deposition methods. These flame synthesis methods may enable future generations of technologies based on metal oxide nanowires to be developed and deployed on a large scale.

Available in PDF, EPUB and Kindle. Book excerpt: Nano-oxide materials lend themselves to applications in a wide variety of emerging technological fields such as microelectronics, catalysts, ceramics, coatings, and energy storage. However, developing new routes for making nano-based materials is a challenging area for solid-state materials chemists. This book does just that by describing a novel method for preparing them. The authors have developed a novel low-temperature, self-propagating synthetic route to nano-oxides by the solution combustion and combustible precursor processes. This method provides the desired composition, structure, and properties for many types of technologically useful nanocrystalline oxide materials like alumina, ceria, iron oxides, titania, yttria, and zirconia, among others.The book is particularly instructive in bringing readers one step closer to the exploration of nanomaterials. Students of nanoscience can acquaint themselves with the actual production and evaluation of nanopowders by this route, while academic researchers and industrial scientists will find answers to a host of questions on nano-oxides. The book also provides an impetus for scientists in industrial research to evaluate and explore new ways to scale up the production of nanomaterials, offering helpful suggestions for further research.

Download or read book Nanoparticle Formation in the Flame Synthesis of Multicomponent Nanostructured Materials for Clean Energy Applications written by Jiaxi Fang and published by . This book was released on 2016 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies the initial stages of particle formation during the combustion synthesis of multicomponent nanomaterials. Combustion is commonly used for the production of nanomaterials at industrial scales and has advantages of high production rates, low waste generation, and scalability. However, there are limitations in being able to apply this synthesis approach to more advanced multicomponent systems. Gas to particle conversion in flames occurs through precursor decomposition, collisional growth, coagulation, condensation, and sintering. There is a fundamental gap in knowledge on the initial stages of particle formation in flames below 2nm due to measurement difficulties and instrumentation limitations. Using a high resolution differential mobility analyzer, the first mobility spectrum measurements of sub 2nm clusters were presented for single component TiO2 and multicomponent SiO2/TiO2 synthesis demonstrating the importance of discrete clusters during particle growth.Further insight into the nature of sub 2nm clusters were gained through the utilization of an atmospheric-pressure time-of-flight mass spectrometer to measure the chemical composition of sub 2nm clusters. During the combustion synthesis of TiO2, it was revealed that for negatively charged species, chemical ionization plays an important role in the formation of TiO2 clusters while large concentrations of high molecular weight organometallic Ti clusters could be measured. Using similar approaches for silica, intermediates of silica clusters could be identified. The main Si growth pathway was revealed to be through silicic acid clusters, where dehydration, hydrogen abstraction, and hydroxyl radical interactions persist through larger clusters of Si. With multicomponent systems of TiO2 and SiO2, evidence of mixed oxide cluster growth could be seen along with independent cluster growth. Mass mobility plots from tandem ion mobility spectrometry-mass spectrometry further revealed that metal oxide cluster masses were much larger than predicted by the widely utilized Kilpatrick relationship used for mass-mobility correlations.The role of ions during combustion synthesis was further studied through measurements of natively charged, charge conditioned, and neutral particle size distributions. Using current voltage measurements in an electric field, the concentration of ions and electric properties of flames were also used to provide insight into ion properties during combustion synthesis for TiO2 and SiO2.Finally, insight from previous studies on the mechanisms of particle formation were applied in developing a system for the synthesis of niobium doped TiO2 nanostructured thin films towards transparent conducting oxide applications. Using a flame aerosol reactor, highly conductive and transparent thin films could be synthesized while enhanced conductivity was achieved through controlled-niobium doping into the anatase crystal lattice of TiO2. Findings from this dissertation have revealed the complexity of gas to particle conversion mechanisms in the initial stages and are the first step towards developing the ability to design flame aerosol reactors for advanced materials synthesis.
