  7. 5. Studies of Catalytic Low-Temperature CO Oxidation over Cobalt Oxide and Related Transition Metal Oxides

    Författare :Jonas Jansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalytic CO oxidation; in-situ XRD; transition metal oxides; low temperature activity; kinetic modelling; in-situ FTIR; in-situ XANES; cobalt oxide; catalyst deactivation; reaction mechanism;

    Sammanfattning : The catalytic oxidation of carbon monoxide at low temperatures is important in many applications. The use of a low temperature active catalyst may lower the emissions during the cold-start of a car, and volatile organic compounds in exhaust gases from stationary sources might be treated without the need of preheating the gas.
