16. Operando Single Particle Catalysis - Combining a Nanoreactor and Plasmonic Nanospectroscopy
Sammanfattning : Heterogeneous catalysis is an important cornerstone of modern society with strong ties to the development of sustainable sources of energy and products. Catalysts are typically realized as supported metal nanoparticles that offer active sites that can accelerate chemical reactions by providing energetically more favorable reaction paths. LÄS MER
17. Fundamental studies of catalytic systems for diesel emission control
Sammanfattning : Due to global lean exhaust gas and new emission regulations, exhaust aftertreatment systems of diesel engines are more and more sophisticated and composed of a series of catalytic units. In the present work, two of these catalytic systems were studied with different approach. LÄS MER
18. Combining Nanoplasmonics and Nanofluidics for Single Particle Catalysis
Sammanfattning : Nanoparticles are, due to their large exposed surface area, widely used in the field of heterogeneous catalysis where they accelerate and steer chemical reactions. Although catalysis has been known about for centuries, the scrutiny of catalysts under realistic application conditions is still a major challenge. LÄS MER
19. Deactivation of after-treatment catalysts for bio-fuelled engines
Sammanfattning : To decrease the emissions of anthropogenic CO2 from vehicles one option is to increase the utilization of biobased fuels. However, there are challenges with this transition, one being the mitigation of emissions of the potent greenhouse gas methane, which is the main constituent of biogas. LÄS MER
20. Catalytic conversion of syngas to ethanol and higher alcohols over Rh and Cu based catalysts
Sammanfattning : The thermochemical process converts almost any kind of biomass to a desired final product, i.e. gaseous or liquid transportation fuels and chemicals. The transportation fuels obtained in this way are renewable biofuels, which are alternatives to fossil fuels. LÄS MER
