Book excerpt: Cerium is one of the most important lanthanide elements based on its characteristics and wide range of related applications. Cerium is the second element in the lanthanide series, and mostly can be found in either +3 or +4 ionisation states. It can be considered one of the rare earth elements with relatively low toxicity and a lot of biological applications depending on its redox (reduction-oxidation) process between the +3/+4 ionisation states and oxygen storage capability. This book focuses on the cerium compounds such as oxides and silicides, with detailed studies about its structures, characterisations and related applications. Chapter One mainly presents some optical characteristics of stoichiometric ceria nanoparticles whether undoped or doped with some other lanthanide elements. Then, some applications of ceria nanoparticles, such as optical nanosensors and solar cell coaters, are discussed based on optical characteristics of CeO2-x. Chapter Two studies the catalytic activity of cerium dioxide (CeO2) included within nanophase (nanocomposite) metal-oxide systems such as Al2O3/cordierite carriers and prototypes of anode materials for SOFCs (based on stabilised zirconia), within different processes of environmental catalysis. CeO2 increases stability of the Ni-Al2O3 catalysts by suppressing surface carbonisation and enhancing resistance to poisoning by sulphur compounds. Cerium dioxide as a modifying additive within the ZnOCuOCeO2/Al2O3/cordierite catalysts is shown to stabilise their operation in the decomposition of methanol by suppressing surface carbonisation, thereby facilitating hydrogen formation as the target product. In Chapter Three, another cerium-dependent compound cerium silicide (CeSix) and its nanowires were investigated over a broad range of different cerium monolayers on Si(110)-16×2 surfaces via scanning, tunnelling, microscopy and spectroscopy. The growth progress of the CeSix nanowires undergoes a coverage-dependent metal-insulator-metal electronic transition, which has never been found in other rare-earth silicide nanowires. Moreover, the insulating CeSix nanowires have been structurally and electronically studied, without lattice distortions with large Coulomb repulsion energy between the filled and empty surface bands. Thus, the insulating phase of atomically precise CeSix nanowires is an electronically driven phase because of its temperature and structure independence. Chapter Four is mainly concerned with some biological applications of ceria nanostructures through the treatment of diseases characterised by increased oxidative stress levels. This chapter offers a study of consumption and occupational exposures, and consequently its toxicology properties are discussed due to the recent applications of nanoceria as a high priority material for toxicological evaluations.

This book was released on 2012 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single crystalline cerium oxide nanoparticles were synthesized with hydrothermal method by mixing cerium nitrate[Ce(NO3)3.6H2O] aqueous solution with alkali bases CsOH and RbOH. SEM, TEM and XRD characterization methods were used in order to identify morphology. First part of the study includes the work on effect of hydrothermal parameters, such as reaction temperature, reaction time, alkali base type and concentration on particle size and morphology. It was prooved that the size of ceria nanoparticles is directly proportional with the reaction time. The reaction temperature is also an important parameter that effect the morphology of nanoparticles. At 120 oC nanoparticles form rod like structure and as time goes they start to form cubic crystals. When the alkali base and concentration was changed the results showed that higher base concentration favors the particles to form bigger structures than that of lower concentrations. In addition, optical properties of CeO2 nanoparticles were studied by using the UV-Vis and Fluorescence Spectrometry. UV-Vis Spectroscopy results show that particle size of CeO2 nanoparticles synthesized in the presence of 8M RbOH are larger than that of synthesized in presence of 8M CsOH. When the reaction time decreases the Ce3+ defect increases based on the results of Fluorescence Spectrometry results. Second part of the study includes catalytic property of CeO2 nanoparticles. Ceria nanoparticles were used as catalyst in the synthesis of flavone from 2'-hydroxychalcone. Several reaction parameters were studied in order to achieve the flavone synthesis. TLC, GC, GC-MS and NMR were used in order to monitor the results of the reactios.

Download or read book Synthesis and Reactivity of Fluorescent Rare earth Doped Cerium Oxide Nanomaterials written by Anne Elizabeth D'Achille and published by . This book was released on 2019 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials based on cerium (IV) oxide, or CeO2, have been investigated due to interesting chemistry from the readily accessible Ce3+/Ce4+ transition. This transition is accompanied by a gain or loss in CeO2 oxygen and/or electrons. As a result, CeO2 has demonstrated reversible antioxidant activity and enzyme mimetic activity, and has also been used in oxygen transport, photocatalysis, and small molecule oxidation applications. Doping CeO2 with lower valent ions creates oxygen vacancies and increases the Ce3+/Ce4+ ratio within the lattice. The dopant may also contribute properties such as fluorescence or magnetism to compliment the CeO2 chemistry. This work presents the synthesis of several europium doped-CeO2 (Eu-CeO2) morphologies, the investigation into parameters controlling their size, morphology, and elemental composition. Select applications highlighting differences in the materials synthesized were also investigated. Eu-CeO2 nanorods and nanocubes were synthesized using a hydrothermal procedure. The nanorods were also annealed to enhance their Eu3+ fluorescence. An electrospinning and annealing procedure was used to synthesize nanowires. The Eu:Ce ratio for all the rods, cubes, and wires were controlled by changing the Eu3+ precursor concentration. Manipulation of the precursor concentrations provided minor dimension control of the rods, while changing of Ce3+ precursor and hydrothermal reaction time influenced the nanocube morphology. Finally, Eu-CeO2 nanotubes have been synthesized by layered deposition of Ce(OH)3 on a sacrificial ZnO nanowire array. The hydroxide was oxidized to Eu-CeO2 and the ZnO core etched to produce the nanotube morphology. The nanotube dimensions were controlled by the ZnO core, but low yield demands further optimization prior to use in the intended drug delivery applications. One synthesized, the rods, cubes, and wires were analyzed for Eu3+-contributed fluorescence. While the cubes and wires fluoresced as synthesized, the nanorods required annealing above 500 °C to fluoresce. Nanocubes were also synthesized with neodymium and ytterbium instead of europium. These cubes fluoresce at 800-1000nm, which is useful in bioimaging applications. The four materials (rods, annealed rods, cubes, and wires) were also compared for their effect on the transformation of di-hydroxyphenylalanine (L-Dopa) to eumelanin. Previous CeO2 nanoparticles have captured catechol-containing molecules by oxidation and conjugation with the -OH groups. Our Eu-CeO2 materials suppressed eumelanin-associated fluorescence by up to 60% when added to L-Dopa early in its transformation to eumelanin. The four morphologies exhibited very different activities, with higher Ce3+ concentrations and smaller crystalline domains associated with enhanced suppression of eumelanin synthesis.
