Elucidating the Effect of Ion Exchange Protocol on the Copper Exchange Efficacy, Copper Siting, and SCR activity in Cu-SSZ-13
Autor: Aibolat Koishybay, Charles Umhey, Chun‐Te Kuo, Kyle Groden, Jean‐Sabin McEwen, Ayman M. Karim, Daniel F. Shantz
The influence of the copper ion exchange protocol on SCR activity of SSZ-13 is quantified. Using the same parent SSZ-13 zeolite, four exchange protocols are used to assess how exchange protocol impacts metal uptake and SCR activity. Large differences

Water Is the Oxygen Source for Methanol Produced in Partial Oxidation of Methane in a Flow Reactor over Cu-SSZ-13
Autor: Aibolat Koishybay, Daniel F. Shantz
Publikováno v: Journal of the American Chemical Society. 142:11962-11966
Direct oxidation of methane to methanol is a long-standing challenge in the heterogeneous catalysis community. This Communication demonstrates that water, not dioxygen, is the main source of the oxygen present in the methanol produced in the partial

The structure directing agent isomer used in SSZ-39 synthesis impacts the zeolite activity towards selective catalytic reduction of nitric oxides
Autor: Ross Ransom, Roger Moulton, Daniel F. Shantz
Publikováno v: Journal of Catalysis. 382:339-346
The selective catalytic reduction of nitric oxide using copper ion-exchanged SSZ-39 is described. Samples made from identical synthesis gels with only different amounts of the trans isomer of the SDA exhibit both different copper metal uptake during

Comparison of Cross-Linked Branched and Linear Poly(ethylene imine) Microgel Microstructures and Their Impact in Antimicrobial Behavior, Copper Chelation, and Carbon Dioxide Capture
Autor: Xiaodong Zhang, Nicholas R. Sandoval, Daniel F. Shantz, Yueyun Lou, Molly E. Payne, Scott M. Grayson, Nurettin Sahiner
Publikováno v: ACS Applied Polymer Materials. 2:826-836
Poly(ethylene imine) (PEI) is a cationic polymer that is commercially available in linear PEI (LPEI) and branched PEI (BPEI) architectures for both biological and environmental applications. When t...

Covalently functionalized uniform amino-silica nanoparticles. Synthesis and validation of amine group accessibility and stability
Autor: Peter Miller, Daniel F. Shantz
Publikováno v: Nanoscale Advances. 2:860-868
This paper describes the synthesis and characterization of colloidally stable, 18 nm silica nanoparticles that are functionalized with amine groups. Electron microscopy, small-angle X-ray scattering (SAXS), and dynamic light scattering show the amine

Zeolite acidity strongly influences hydrogen peroxide activation and oxygenate selectivity in the partial oxidation of methane over M,Fe-MFI (M: Ga, Al, B) zeolites
Autor: Meysam Shahami, Daniel F. Shantz
Publikováno v: Catalysis Science & Technology. 9:2945-2951
The partial oxidation of methane to oxygenates, primarily formic acid, over a series of Fe-MFI zeolites with different trivalent framework atoms is reported. Numerous characterization techniques were used to confirm the crystallinity, composition, te
