26. Photocatalysis for Indoor Air Cleaning : In situ FTIR and DFT Study of Acetaldehyde Photo-Oxidation on TiO2 and Sulfate-Modified TiO2
Sammanfattning : Acetaldehyde is among the group of VOC’s causing the so-called "sick building" syndrome. WHO has estimated that this problem, related to the indoor air-quality, affects one third of all buildings worldwide. TiO2 is an attractive material for the photocatalytic removal of VOC’s in the indoor environment. LÄS MER
27. Direct conversion of methane-to-methanol in Cu-exchanged small-pore zeolites
Sammanfattning : Fossil fuel consumption continuous to increase worldwide and of all the fossil fuels, natural gas is growing the most. The combustion of natural gas, which mainly contains methane, is more environmentally friendly than oil or coal thanks to its high specific energy. LÄS MER
28. Exploring the Surface of Aqueous Solutions : X-ray photoelectron spectroscopy studies using a liquid micro-jet
Sammanfattning : The surface behavior of biologically or atmospherically relevant chemical compounds in aqueous solution has been studied using surface-sensitive X-ray photoelectron spectroscopy (XPS). The aim is to provide information on the molecular-scale composition and distribution of solutes in the surface region of aqueous solutions. LÄS MER
29. Capturing Air Pollutants : Photochemical Adsorption and Degradation of SO2, NO2 and CO2 on Titanium Dioxide
Sammanfattning : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. LÄS MER
