Book excerpt: This thesis presents a study of the effect of chemical modifiers and dopants on both the anatase to rutile transformation and also the photocatalytic efficiency of semiconductor nanomaterials. The main focus of the work is based on the crystallisation and phase transformation of the widely investigated semiconductor metal oxide, titanium dioxide (TiO2) Of the three polymorphs associated with titanium dioxide, anatase is widely regarded as the most effective photocatalyst. Typically anatase will transform to rutile in the temperature range 600 - 700 °C however, modification of a titanium precursor with a chelating agent can result in extended transformation temperature. The effect of employing various concentrations of formic acid and water on phase transition is systematically studied by XRD, FTIR and Raman spectroscopy (Chapter 3). Retention of anatase (41%) at increased temperatures (800 °C) and 10% at 900 °C is achieved at optimum conditions. On comparison, a control sample prepared without modification with formic acid show rutile formation at 600 °C. FTIR and Raman studies indicate that a bridging titanium-formate structure is formed upon addition of titanium isopropoxide to formic acid. It is proposed that under different reaction conditions, a syn-syn or synanti bridging structure is favoured. It is concluded that the syn-anti bridging structure hinders cross linking of the metal oxide oligomer network, resulting in a weakened structure, facilitating low temperature rutile formation when compared with the syn-syn binding mode which forms a more ordered network, stabilising anatase at increased temperatures. Using the optimum formic acid, titanium isopropoxide molar ratios (TTIP:FA:H2O, 1:4:4) obtained in chapter 3, silver (1, 3 and 5 mol %) was added to the system and the effects are reported (chapter 4). Through XRD it is shown that silver lowers the anatase to rutile transformation temperature. Samples calcined at 700 °C show that 5 mol % Ag-TiO2 contains b.

Available in PDF, EPUB and Kindle. Book excerpt: Versatility, extended compositional ranges, better homogeneity, lesser energy consumption, and requirement of nonexpensive equipments have boosted the use of sol-gel process on top of the popularity in the synthesis of nanosystems. The sol-gel technique has not only revolutionized oxide ceramics industry and/or material science but has also extended widely into multidimensional applications. The book Recent Applications in Sol-Gel Synthesis comprises 14 chapters that deal mainly with the application-oriented aspects of the technique. Sol-gel prepared metal oxide (MO) nanostructures like nanospheres, nanorods, nanoflakes, nanotubes, and nanoribbons have been employed in biomedical applications involving drug deliveries, mimicking of natural bone, and antimicrobial activities. The possibility of controlling grain size in aerogel and preparation of ultrahigh-temperature ceramic (UHTC)-based materials, fluorescent glasses, ultraviolet photosensors, and photocatalysts have been discussed in detail by the experts in the field. The usefulness of sol-gel materials as active GRIN, as textile finisher, and as leather modifier with water-repellent and oil-resistive properties would be an incentive for researchers keen to pursue the field.

Book excerpt: Doctoral Thesis / Dissertation from the year 2011 in the subject Chemistry - Materials Chemistry, East China University of Science and Technology (-), language: English, abstract: Considerable effort has been made to design, fabricate, and manipulate nanostructured materials by innovative approaches. The precise control of nanoscale structures will pave the way not only for elucidating unique size/shape dependent physicochemical properties but also for realizing new applications in science and technology. Nanotechnology offers unprecedented opportunities for improving our daily lives and the environment in which we live. This thesis mainly describes recent progress in the design, fabrication, and modification of nanostructured semiconductor materials for environmental applications. The scope of this thesis covers TiO2, Bi2O3 and BiOCl materials, focusing particularly on TiO2-based nanostructures (e.g., pure, doped, coupled, mesoporous, hierarchically porous, and ordered mesoporous TiO2). Mesoporous titania is of particular interest since this class of materials possesses well-defined porosity and large specific surface areas. For photocatalytic degradation of organics, these desirable properties are anticipated to improve the efficiency. So in the first part of work, I have synthesized the mesoporous titania by using poly ethylene glycol as a template in dilute acetic acid aqueous solution by hydrothermal process and investigated the effect of PEG molecular weights and thermal treatment on the resultant structure and photocatalytic activity. When the molecular weights of PEG vary from 600 to 20,000, the particle sizes of mesoporous-TiO2 structure decrease from 15.1 to 13.3 nm and mean pore sizes increase from 6.9-10.6 nm. The activities of these mesoporous-TiO2 photocatalysts prepared by using PEG are evaluated and compared with Degussa P-25 using chloro-phenol as a testing compound. [...]

Available in PDF, EPUB and Kindle. Book excerpt: Since Dr. Disiich of Germany prepared a glass lens by the sol-gel method around 1970, sol-gel science and technology has continued to develop. Since then this field has seen remarkable technical developments as well as a broadening of the applications of sol-gel science and technology. There is a growing need for a comprehensive reference that treats both the fundamentals and the applications, and this is the aim of Handbook of Sol-Gel Science and Technology. The primary purpose of sol-gel science and technology is to produce materials, active and non-active including optical, electronic, chemical, sensor, bio- and structural materials. This means that sol-gel science and technology is related to all kinds of manufacturing industries. Thus Volume 1, Sol-Gel Processing, is devoted to general aspects of processing. Newly developed materials such as organic-inorganic hybrids, photonic crystals, ferroelectric coatings, photocatalysts will be covered. Topics in this volume include: Synthesis and reaction of sol-gel precursors, Preparation of bulk glass and ceramics, Processing of porous materials based on self-organization, Synthesis of organic-inorganic hybrid materials, Coating of plastics, Special processes used in sol-gel formation of materials (1. Non-hydrolytic sol-gel process, 2. Sonogels, and 3. UV irradiation). Volume 2, Characterization of Sol-Gel Materials and Products, highlights the important fact that useful materials are only produced when characterization is tied to processing. Furthermore, characterization is essential to the understanding of nanostructured materials, and sol-gel technology is a most important technology in this new field. Since nanomaterials display their functional property based on their nano- and micro-structure, "characterization" is very important. Topics found in Volume 2 include: Determination of structure by NMR, In-situ characterization of the sol-gel reaction process, Determination of microstructure of oxide gels, Characterization of porous structure of gels by the surface measurements, Characterization of organic-inorganic hybrid, Measurements of rheological properties, Measurements of functional properties: fluorescence, laser, non-linear optical and other properties. Sol-gel technology is a versatile technology, making it possible to produce a wide variety of materials and to provide existing substances with novel properties. This technology was applied to producing novel materials, for example organic-inorganic hybrids, which are quite difficult to make by other fabricating techniques, and it was also applied to producing materials based on high temperature superconducting oxides. Volume 3, Applications of Sol-Gel Technology, will cover applications such as: Application of sol-gel method to processing of bulk silica glasses, Bulk porous gels prepared by sol-gel method, Application of sol-gel method to fabrication of glass and ceramic fibers, Reflective and antireflective coating films, Planar waveguides prepared by sol-gel method, Films with micropatterns and two-dimensional photonic crystals, Application of sol-gel method to formation of ferroelectric films, Application of sol-gel method to formation of photocatalytic coating films, Application of sol-gel method to bioactive coating films.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reported synthesis of TiO2 nanostructures and Fe2O3 nanostructures and studied on self-assembling process. The morphologies, compositions, and physicochemical properties of the prepared samples were characterized by TEM, FESEM, XRD, FTIR, UV, and SQUID etc. Nanoparticles of transition metal oxides own their special function to become an interesting hot research topic in the recent decades. In particular, superparamagnetic iron oxide nanoparticles can be used as drug delivery agent and new hard disc drive materials. They have wide application in environment industry as well. Titanium dioxide nanoparticles can be applied in photocatalysts, UV protectors and dye sensitive solar cell etc. Their wide industrial applications for advanced technology development motivate scientists to develop simple, economical and novel synthetic methods, and explore their applications, so that the commercialization of the production of the nanomaterials becomes feasible. The objective of this project is to develop an effective, simple and economical technical route for synthesis of nanosized iron oxide and titanium oxide particles/rods/films. The approach and the progress are outlined as follows. Based on extensive literature reading on the project related area, a novel self-assembling technical route for iron oxide nanostructure and architecture was proposed which has been confirmed to be effective. Detailed experimental investigation on the synthesis of nanoparticles/rods, and instrumental characterization of the particle size, structure, and crystallites, etc. via TEM, FESEM, XRD, FTIR, UV, SQUID are conducted. Uniform nanorods of hematite iron oxide and titanium oxide nanospheres, and anatase TiO2 thin film with micropores have been successfully achieved. Some preliminary exploration for applications of the synthesized nanomaterials has also been carried out. Firstly, a novel assembled scheme of iron oxide nanostructure and architecture by selfassembling process was investigated. The sol-gel technical route was employed to synthesize nearly uniform nanorods of hematite particles. Morphologies and physicochemical properties of iron oxide nanostructure were characterized by analytical instrument. Secondly, titanium oxide nanospheres were synthesized via a hydrothermal process using titanium isopropoxide as the precursor. Titanium oxide nanospheres with inner nanospace andhighly organized crystallites in the shell structure and surface regions were synthesized. It demonstrated that the technical route developed in this work has a high versatility for structural engineering of various targeted morphological products. Thirdly, a simple process of preparing anatase TiO2 thin film with micropores was pursued. The synthesized nano thin film with micropores was used for the material of dye-sensitive solar cell; and effective electron transfer of titanium oxide electrode was confirmed by electrochemical voltammetry. Preparation of the titanium oxide electrode and its electrochemical analysis was studied. The application of the titanium oxide of microporous thin film material as a promoter for electrochemistry voltammetry measuring system was explored in this thesis. In conclusion, the iron oxide nanorods with superparamagnetic property were successfully synthesized by a simple method with low cost materials. Titanium oxide hollow nanospheres were achieved by the assistance of copolymer template. Titanium oxide thin film with microporous structure with significantly high efficiency in electron transfer was realized. Further researches on the synthesis of hybrid iron oxide and titanium oxide nanoparticles, their crystal growth architecture and mechanism, as well as exploration of their applications are recommended.
