2. The active phase of Pt(110) during catalytic CO oxidation
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. READ MORE

3. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE

4. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for NanoscienceAbstract : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.

5. Ethylene to Liquid Hydrocarbons by Heterogeneously Catalyzed Oligomerization on ZSM-5
University essay from Uppsala universitet/Fysikalisk kemiAbstract : The aim is to produce aliphatic liquid hydrocarbons using heterogeneous ethylene oligomerization. Thiscould potentially produce renewable synthetic fuels. Heterogeneous catalysis has some advantages overhomogeneous catalysis regarding some sustainability aspects. READ MORE
