1. Enzyme Immobilization in Mesoporous Silica
Sammanfattning : Catalysts are widely used in many industries for production of chemicals, pharmaceuticals, fuels and energy. There is a need for more sustainable production processes, with reduced energy and raw material consumption together with a reduction in waste and toxic by-products. LÄS MER
2. Biocide Release and Use of Mesoporous Materials as Support for Transition Metal Catalysts
Sammanfattning : .... LÄS MER
3. Nanostructured Catalysts and Electrode Materials for PEM Fuel Cells
Sammanfattning : The Polymer Electrolyte Membrane Fuel Cell (PEMFC) is a promising energy converting technology for powering automotives and electrical equipment using hydrogen gas as fuel and producing water as the only exhaust. The active carbon-supported platinum catalyst present in the electrodes limits the maximum power generation in state-of-the-art PEMFCs due to platinum’s poor activity for the oxygen reduction reaction (ORR) taking place at the cathode.

4. Functionalized mesoporous carbons as non-precious metal fuel cell catalysts
Sammanfattning : Fuel cells allow for clean and efficient chemical to electrical energy conversion. However, their high price significantly limits the market viability of the technology. This is to a large part due to the high cost of the precious metals used in most fuel cell catalysts. LÄS MER
5. Enzyme immobilization in mesoporous silica
Sammanfattning : Enzymes are highly effective and versatile biological catalysts, with a high chemo-, stereo- and regioselectivity while operating under mild conditions, such as physiological temperature and pH and atmospheric pressure. Therefore, enzymes are a sustainable alternative to conventional catalysts in organic synthesis processes. LÄS MER
