1. Studies of the Selective Catalytic Reduction of Nitrogen Oxides with Dimethyl Ether
Abstract : Dimethyl ether (DME) is one of the most energy-efficient and low CO2 emitting alternative fuels when produced from biomass. Similar to other vehicles with combustion engines, vehicles running on DME will most likely need after-treatment technologies for the reduction of NOx emissions to meet the most stringent upcoming legislations.

2. 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
