Journal ArticleDOI
Dynamic multinuclear sites formed by mobilized copper ions in NO x selective catalytic reduction.
Christopher Paolucci,Ishant Khurana,Atish A. Parekh,Sichi Li,Arthur J. Shih,Hui Li,John R. Di Iorio,Jonatan D. Albarracin-Caballero,Aleksey Yezerets,Jeffrey T. Miller,W. Nicholas Delgass,Fabio H. Ribeiro,William F. Schneider,Rajamani Gounder +13 more
TL;DR: It is demonstrated that under reaction conditions, mobilized Cu ions can travel through zeolite windows and form transient ion pairs that participate in an oxygen (O2)–mediated CuI→CuII redox step integral to SCR.
Journal ArticleDOI
Catalysis in a Cage: Condition-Dependent Speciation and Dynamics of Exchanged Cu Cations in SSZ-13 Zeolites
Christopher Paolucci,Atish A. Parekh,Ishant Khurana,John R. Di Iorio,Hui Li,Jonatan D. Albarracin Caballero,Arthur J. Shih,Trunojoyo Anggara,W. Nicholas Delgass,Jeffrey T. Miller,Fabio H. Ribeiro,Rajamani Gounder,William F. Schneider +12 more
TL;DR: Experimental and theory together reveal that the Cu sites respond sensitively to exposure conditions, and in particular that Cu species are solvated and mobilized by NH3 under SCR conditions.
Journal ArticleDOI
Isolation of the Copper Redox Steps in the Standard Selective Catalytic Reduction on Cu‐SSZ‐13
Christopher Paolucci,Anuj A. Verma,Shane A. Bates,Vincent F. Kispersky,Jeffrey T. Miller,Rajamani Gounder,W. Nicholas Delgass,Fabio H. Ribeiro,William F. Schneider +8 more
TL;DR: Operando X-ray absorption experiments and density functional theory (DFT) calculations are reported that elucidate the role of copper redox chemistry in the selective catalytic reduction (SCR) of NO over Cu-exchanged SSZ-13.
Journal ArticleDOI
Identification of the active Cu site in standard selective catalytic reduction with ammonia on Cu-SSZ-13
Shane A. Bates,Anuj A. Verma,Christopher Paolucci,Atish A. Parekh,Trunojoyo Anggara,Aleksey Yezerets,William F. Schneider,Jeffrey T. Miller,W. Nicholas Delgass,Fabio H. Ribeiro +9 more
TL;DR: In this article, the standard selective catalytic reduction (SCR) reaction at 473 K with 320 ppm NO, 320 ppm NH 3, 10% O 2, 8% CO 2, and 6% H 2 O was observed to track with a hydrated Cu(II) species in ultraviolet-visible-near infrared spectroscopy (UV-Vis-NIR) at ambient conditions.
Journal ArticleDOI
NO oxidation: A probe reaction on Cu-SSZ-13
Anuj A. Verma,Shane A. Bates,Trunojoyo Anggara,Christopher Paolucci,Atish A. Parekh,Krishna Kamasamudram,Aleksey Yezerets,Jeffrey T. Miller,W. Nicholas Delgass,William F. Schneider,Fabio H. Ribeiro +10 more
TL;DR: In this article, the site requirements and mechanism of dry NO oxidation were examined on a series of Cu-SSZ-13 catalysts (silicon/aluminum atomic ratio 4.5) with Cu:total-aluminum (Cu/Al tot ) atomic ratios ranging from 0.02 to 1.6.
