The CHASS project tackles the harmful nitrogen oxides emissions from heavy-duty diesel vehicles by focusing on improving copper-based catalysts. These catalysts, crucial for reducing emissions,…
Our latest review in ChemCatChem examines the significant role of the [(NH3)4Cu2O2]2±peroxo complex in NH3-SCR processes using Cu-CHA catalysts at low temperatures (150–300°C). This complex,…
In this work, we use DFT calculations to compare the dealumination mechanisms in H–CHA and Cu–CHA and elucidate the enhanced hydrothermal stability of Cu–CHA. we…
This article investigates the influence of SO2 exposure on Cu-CHA catalysts, which were pre-treated to ensure specific Cu speciations. We employed in situ diffuse reflectance UV-vis…
This study investigates the commonly used H2-TPR procedure, combining first principle calculations to unravel the Cu ions responsible for H2 consumption. “Interpretation of H2-TPR from…
Excited to share our study on the sulfur-induced deactivation of Cu-CHA during NH3-SCR conditions, by presenting a detailed mechanism based on first principle calculations. Density…
