  2. 1. New Materials in Environmental Catalysis

    Author : Magnus Skoglundh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cobalt; Copper; Xylene oxidation; Platinum; Carbon monoxide oxidation; exhaust gas catalysis; Rhodium; Palladium; Nitric oxide reduction; perovskites;

    Abstract : 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.

  4. 2. Synthesis of functionalized allylic, propargylic and allenylic compounds : Selective formation of C–B, C–C, C–CF3 and C-Si bonds

    Author : Tony Zhao; Kálmán Szabó; Hajime Ito; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium catalysis; allylboration; allenylboration; trifluoromethylation; silylation; copper catalysis; borylation; bimetallic catalysis; organisk kemi; Organic Chemistry;

    Abstract : This thesis is focused on the development of new palladium and copper- mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. The synthetic utility of the 1,2-diborylated butadienes synthesized in one of these processes has also been demonstrated. READ MORE

  5. 3. Biomimetic Transition Metal Catalysts : Insights from Theoretical Modeling

    Abstract : The nitrogen atom plays a unique role in organic chemistry. It is abundantly found in organic materials and is responsible for the activity of many biologically relevant compounds. READ MORE

  7. 5. Direct conversion of methane-to-methanol in Cu-exchanged small-pore zeolites

    Author : Unni Engedahl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; partial methane oxidation; SSZ-13; density functional theory; catalysis; micro-kinetic modeling; zeolites; CHA; copper;

    Abstract : Fossil fuel consumption continuous to increase worldwide and of all the fossil fuels, natural gas is growing the most. The combustion of natural gas, which mainly contains methane, is more environmentally friendly than oil or coal thanks to its high specific energy. READ MORE
