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

5. New Materials in Environmental Catalysis
Sammanfattning : This thesis presents new approaches to the control of emissions within the field of environmental catalysis. Three catalytic systems; bimetallic catalysts, perovskites and promoted catalysts have been prepared and evaluated for complete oxidation of volatile organic compounds and for simultaneous conversion of CO, hydrocarbons and nitrogen oxides.
