1. Reaction kinetics of NH3-SCR over Cu-CHA from first principles
Abstract : Ammonia assisted selective catalytic reduction (NH3-SCR) is a leading technology that is used for NOx reduction to N2 and H2O in oxygen excess. Thanks to its high activity, high selectivity, and durability, Cu-CHA is commercialized as an NH3-SCR catalyst. READ MORE

2. Reaction kinetics of NH3-SCR over Cu-CHA from first principles
Abstract : Ammonia-assisted selective catalytic reduction (NH3-SCR) is an advanced technology to reduce nitrogen oxide (NOx) emissions from lean-burn engines. NH3 is added to the exhaust gas and reacts selectively with NOx, forming N2 and H2O. READ MORE

3. Reactions on nanostructured and microporous surfaces
Abstract : Interactions between surfaces and molecules play a central role in various fields where catalysis is one example. In order to understand different surface processes, physicochemical characterisation of the surface materials and molecules is required. READ MORE

4. Dynamics and Reactivity of Cu-species in Cu-CHA for NH3-SCR
Abstract : Copper exchanged chabazite (Cu-CHA) is a state-of-the-art catalyst for deNOx via ammonia assisted selective catalytic reduction (NH3-SCR) in lean burn engines, owing to its good low-temperature activity, and high hydrothermal stability. One challenge for Cu-CHA is, however, the sensitivity to sulfur species, which are present in the exhaust gas. READ MORE
