  1. 1. Catalysts for Oxygen Production and Utilization Closing the Oxygen Cycle: From Biomimetic Oxidation to Artificial Photosynthesis

    Detta är en avhandling från Stockholm : Department of Organic Chemistry, Stockholm University

    Författare :Erik Karlsson; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxygen; catalytic oxidation; biomimetic oxidation; artificial photosynthesis; water oxidation; DFT calculations; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis describes the development and study of catalysts for redox reactions, which either utilize oxygen or hydrogen peroxide for the purpose of selectively oxidizing organic substrates, or produce oxygen as the necessary byproduct in the production of hydrogen by artificial photosynthesis.The first chapter gives a general introduction about the use of environmentally friendly oxidants in the field of organic synthesis, and about the field of artificial photosynthesis.

  4. 4. Design and Operation of a 10 kWth Chemical-Looping Combustor for Solid Fuels

    Detta är en avhandling från Department of Anaesthesiology and Intensive Care, Lund

    Författare :Nicolas Berguerand; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Fuel Conversion; Chemical-Looping Combustion; Oxygen Carrier; Ilmenite; Carbon Dioxide Capture; Oxygen Transfer; Gas Conversion; Oxygen Demand;

    Sammanfattning : Chemical-looping combustion (CLC) is a new fuel conversion technology with inherent CO2 capture. In this process, the fuel and the combustion air are never mixed and the oxygen is transferred to the fuel via an oxygen carrier in the form of a metal oxide circulating between two reactors, e.g. LÄS MER

  5. 5. Oxygen Vacancy Chemistry in Ceria

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jolla Kullgren; Uppsala universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ceria; Density Functional Theory; Oxygen storage; Nano crystals; Sulfur poisoning; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Cerium(IV) oxide (CeO2), ceria, is an active metal oxide used in solid oxide fuel cells and for the purification of exhaust gases in vehicle emissions control. Behind these technically important applications of ceria lies one overriding feature, namely ceria's exceptional reduction-oxidation properties. LÄS MER
