Book excerpt: With increasing energy costs, government regulations, and an expanding population, alternative low-cost methods for the treatment of waste air and water have shown renewed interest. The utilization of solar energy to promote catalytic reactions, including photodegradation of pollutants, is an attractive and well-established field of research. Titanium dioxide nanoparticles are the most widely employed catalyst material in photocatalytic studies. Owing to its high surface area and electronic structure, the anatase phase of TiO 2 is an excellent photocatalyst. However, a detailed understanding of the physical, chemical, and electronic properties of TiO 2 that influence the photocatalytic reaction rate does not exist. One goal of this work is the determination of how the degradation rate over TiO 2 nanoparticle is influenced by the particle size. To meet this goal, detailed analysis of the particles was carried out using standard catalytic techniques combined with infrared spectroscopy to probe the decomposition of an organic probe molecule, formic acid. It was shown using infrared spectroscopy that the size of the particle does influence the rate of photodegradation. However for particles as small as five nanometers, the increased rate could be described by accounting for the increased surface area of the particles. Novel synthesis conditions for the synthesis of high purity particles is required to develop a better understanding of how the size can influence the particle's catalytic properties. Combustion synthesis serves as an attractive method for the synthesis of high purity TiO 2 nanoparticles. The high temperatures present in a combustion flame promotes the decomposition of organometallic precursors and subsequent synthesis of metal oxide nanoparticles. Numerous synthesis conditions can influence the product powder. This research investigated some of these conditions for the synthesis of TiO 2 nanoparticles. Additionally the thermal properties of TiO 2 nanoparticles was investigated. It is known that the more active phase for photocatalysis, anatase, is metastable at extremely small particle sizes (

Available in PDF, EPUB and Kindle. Book excerpt: Titanium dioxide (TiO2) has received a lot of attention due to its inexpensive cost, benign nature, and great photocatalytic potential. TiO2 has numerous applications, including in photocatalysts, Li-ion batteries, solar cells, and medical research. However, its performance is unsatisfactory due to a variety of issues, including a wide band gap (3.01 to 3.2 eV) and quick electron–hole pair recombination (1012 to 1011 s). Many efforts have been made to improve the qualities of TiO2, such as structural and dopant changes, which expand its applications. This book focuses on the properties of TiO2-modified nanoparticles, including their synthesis, alterations, and applications.

Download or read book Computational Study of Water Over Titanium Dioxide Surfaces written by Srinivas Chakravarthy Mushnoori and published by . This book was released on 2017 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the potential of Titanium Dioxide as a source of alternative energy, drug delivery, protein adsorption, etc. it is imperative that the underlying mechanism of surface-water interactions be thoroughly understood. To this end, our study employs Molecular Dynamics simulations to establish a nanoscale, all atomistic model to capture the mechanistics of the interfacial interactions of water with a Titanium Dioxide surface. Two polymorphs of Titanium Dioxide, Anatase (101) and Rutile (110), are simulated and various aspects of their interfacial behavior studied. Further, a comparison is made between two different electrostatic models, namely, the Multi- Level Summation and the Screened Coulomb potential. The outcome of these studies can guide the adoption of suitable electrostatic potentials for examining bulk-scale behavior in titania-water systems. To this end, a specific case of Titanium Dioxide decorated with Platinum atoms is studied using the Screened Coulomb potential.
