Cu‐SSZ‐13 Catalysts Designed Through Interzeolite Conversion Process From Different Structure Types of Zeolites for NH3‐SCR‐DeNOx: Structure‐Property Activity Relationships and Intermediates Determination

open access: yesChemCatChem, EarlyView.
A set of Cu‐SSZ‐13 zeolite samples (CHA structure type) was designed and developed to employ different starting zeolite materials (i.e., FAU, BEA, MFI). The investigations provide a pathway to gain deeper insights into the relationships between the structure and activity of these zeolite‐based materials in NH3‐SCR‐DeNOx.

Effect of pH on the Electrochemical Reduction of Nitrate on Metallic Copper

open access: yesChemCatChem, EarlyView.
The electrochemical reduction of nitrate on Cu was investigated between pH 4.4–9.3 using on line DEMS and in situ FTIR. We show that electrolyte pH governs the stabilization and conversion of key intermediates such as NO, N2O, and N2H4, and alters local interfacial conditions.
