    Sammanfattning : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. LÄS MER

  7. 5. Supported Mono- and Bimetallic Gold Nanoparticle Catalysts for Different Organic Transformations

    Författare :Sheetal Sisodiya; Centrum för analys och syntes; []
    Nyckelord :Gold nanoparticles; coupling reaction; styrene epoxidation; bimetallic nanoparticle; supported gold nanoparticle;

    Sammanfattning : Supported gold nanoparticles are emerging as an important class of catalysts for various organic transformations due to their tunable properties. This thesis embraces the fundamental studies of supported gold nanoparticles for different organic reactions from the viewpoint of understanding the role of synthesis methods, nature of carriers, and addition of second metal on the properties and functions of gold catalysts.
