  1. 11. Low-Temperature Oxidation of CO and Volatile Organic Compounds over Supported Platinum Catalysts

    Författare :Karl Arnby; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hexamethyldisiloxane; alumina; catalytic deactivation; environmental catalysis; platinum; volatile organic compounds; carbon monoxide; low-temperature activity;

    Sammanfattning : The catalytic oxidation of carbon monoxide (CO) and volatile organic compounds (VOC) is important for the reduction of harmful emissions from both vehicles and from stationary sources. Both these applications suffer from poor catalytic efficiency at lower temperatures. LÄS MER

  3. 12. PEPPSI-type Complexes of Palladium and Platinum: : Investigation of Properties and Applications in Catalysis

    Författare :Ekaterina Bolbat; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEPPSY-type complexes; palladium; platinum; C−H activation; supported homogeneous catalysts;

    Sammanfattning : Catalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate. Special compounds used forthis purpose are called catalysts; they induce a change in the chemicalenvironment without being consumed during the process. LÄS MER
