1. Kinetics of Nanoparticle Catalysis from First Principles
Sammanfattning : Modern society depends heavily on heterogeneous catalysis, which creates strong economical and environmental incentives to improve catalyst efficiency. Heterogeneous catalysts are often realized as metal nanoparticles (NPs) supported on oxide surfaces, and catalysts are traditionally developed by trial and error approaches. LÄS MER
2. Transient Phenomena in CO and Hydrocarbon Oxidation over Supported Platinum Catalysts
Sammanfattning : The aim with this thesis work was to better understand transient phenomena involved in the low-temperature oxidation of CO and hydrocarbons by oxygen over typical oxidation catalysts. Supported platinum catalysts were prepared and carefully studied under transient conditions by means of flow-reactor experiments, different in situ spectroscopic (FTIR and XANES) methods in combination with mass spectrometry and mean-field kinetics simulations.

3. Low temperature CO oxidation: Effects of support, composition and structure
Sammanfattning : Carbon monoxide is a tasteless, colorless and in-odorous toxic gas, which is formed during incomplete combustion. Due to its toxicity, efficient methods for CO oxidation to CO2 are required. LÄS MER
