Appraising Multinuclear Cu2+ Structure Formation in Cu‐CHA SCR Catalysts via Low‐T Dry CO Oxidation with Modulated NH3 Solvation
Autor: Umberto Iacobone, Prof. Dr. Isabella Nova, Prof. Dr. Enrico Tronconi, Dr. Roberta Villamaina, Dr. Maria Pia Ruggeri, Dr. Jillian Collier, Dr. David Thompsett
Publikováno v: ChemistryOpen, Vol 11, Iss 9, Pp n/a-n/a (2022)
Abstract Cu2+ ions (ZCu2+(OH)−, Z2Cu2+) are regarded as the NH3‐SCR (SCR=selective catalytic reduction) active site precursors of Cu‐exchanged chabazite (CHA) which is among the best available catalysts for the abatement of NOx from Diesel engi

The H2O Effect on Cu Speciation in Cu-CHA-Catalysts for NH3-SCR Probed by NH3 Titration
Autor: Roberta Villamaina, Federica Gramigni, Umberto Iacobone, Shaojun Liu, Isabella Nova, Enrico Tronconi, Maria Pia Ruggeri, Jillian Collier, Andrew P. E. York, David Thompsett
Publikováno v: Catalysts, Vol 11, Iss 7, p 759 (2021)
The present work is focused on the effect of water on NH3 adsorption over Cu-CHA SCR catalysts. For this purpose, samples characterized by different SAR (SiO2/Al2O3) ratios and Cu loadings were studied under both dry and wet conditions. H2O adversely

Transient CO Oxidation as a Versatile Technique to Investigate Cu2+ Titration, Speciation and Sites Hydrolysis on Cu–CHA Catalysts: The Cu Loading Effect
Autor: Umberto Iacobone, Isabella Nova, Enrico Tronconi, Roberta Villamaina, Maria Pia Ruggeri, Jillian Collier, David Thompsett
Publikováno v: Topics in Catalysis.
The investigation of the ZCu2+(OH)− and Z2Cu2+ ions modifications during NH3-SCR on Cu–CHA catalysts is a key aspect to clarify the still-debated low-T redox SCR mechanism. In previous works, the dry transient CO oxidation protocol has been emplo

AdSCR Systems (Adsorption + Selective Catalytic Reduction): Analysis of the Influence of H2O and CO2 on Low Temperature NOx Emission Reduction Performances
Autor: Isabella Nova, Enrico Tronconi, Federica Gramigni, Nicole Daniela Nasello
Publikováno v: Emission Control Science and Technology. 7:223-231
The removal of NOx from low-temperature diesel engine emissions still represents a big challenge in view of the upcoming more stringent worldwide regulations. In our previous studies, we proved the ability of novel AdSCR (Adsorption + Selective Catal

Transient Kinetic Analysis of Low-Temperature NH3-SCR over Cu-CHA Catalysts Reveals a Quadratic Dependence of Cu Reduction Rates on CuII
Autor: Shaojun Liu, Umberto Iacobone, Nicola Usberti, Federica Gramigni, Xiang Gao, Wenshuo Hu, Nicole Daniela Nasello, Enrico Tronconi, Isabella Nova, Tommaso Selleri
Publikováno v: ACS Catalysis. 11:4821-4831
We combine gas phase Transient Response Methods with Transient Kinetic Analysis to investigate the reduction half-cycle (RHC: CuII → CuI) of the Standard SCR redox mechanism over Cu-CHA (chabazite)...
